Each axis will run towards its limit switch until it engages the switch, then will run the opposite way until the switch disengages. The Performance Upgrade is a new product that allows you to convert your D-Series D.840, D.600, or D.420 to dual Y axis motors thus eliminating the drive belt and increasing performance from 50 mm/sec to 70 mm/sec. On a STEPCRAFT, the homing procedure begins with the Z-Axis, then the X-Axis and finally the Y-Axis. HOMING_BACKOFF_MM is redundant imo especially if you are also using MANUAL_ (XYZ)_HOME_POS. The code responsible for this is found in G28.cpp: I.e. This is the target z after z homing and if that is set 0 it would go down. But the history of the Safe Homing was because the probe offset from the nozzle was causing problems. When I use 1.1.9 all my stepper direction is fine ( homing and linear moves ) When ported all the same setting to Marlin 2.0.7.2 based firmware homing direction is reversed but manual travel direction is fine ( G1 X Y Z is fine too ) I was bashing my head and cannot wrap my brain around what is going on, It just suppose to work. The positioning light is a class 2 laser with far less power (comparable to a laser pointer). Without abl, you are solving for 2 unknowns. This software will also allow you to create a 4th axis job. Every post processor used with a STEPCRAFT machine should end in (mm). After flashing Marlin software, the extruder keeps homing at X77 Y50 instead of X150 Y150 that is the center of the printing area for me. A place where one lives; a residence. It is a very common mistake to select the (inch) post processor when working in inches. I have a printer with the following dimensions: L300 x W300 x H400. The next step is to mount homing sensors on the machine. If compare to the latest (v1.1.9) Configuration.h file from GitHub, here are the changes: Sign in to view But yes you can alter the values if you want, but that wouldn't be necessary. My probe IS the nozzle, not something mounted on the carriage. StallGuard capable TMCxxxx stepper driver 2. By using a surfacing bit, you will ensure that your spoil board is perfectly level in relation to your gantry which will result in a uniform engraving. As a side-effect, X and Y homing are required before Z homing. After downloading and installing version 1.2049 of UCCNC, the Jog Pendant should now be visible in the configuration window and you can proceed with the rest of the setup! That being said, you still need a method of controlling the CNC machine, which is where programs like Mach 3 and UCCNC come in. Z-Probe AND Z-Sensorless Homing? A $60 end mill bit the dust in the process before I could stop it. Move the laser head approx. // One just need to home the Z axis and measure the distance difference between both Z axis and apply the math: Z adjust = Z - Z2. MathJax reference. is set to. If you enabled Z_SAFE_HOMING, then automatically the printer homes Z at the middle of the build plate, if the bed size dimensions are correctly defined (in your case X_BED_SIZE and X_BED_SIZE should be defined as 300). Use MathJax to format equations. guiding or directing homeward or to a destination, especially by mechanical means: the homing instinct; a homing beacon. To connect your remote switchable power controller system, follow the diagram below…, The following support videos will help walk you through aligning your X-Axis on a STEPCRAFT D.Series machine …, Here is a video showing you how to do the cleaning and greasing procedure, An Example of an Aligned Stepcraft Machine, X Axis Alignment – Disassembling the X Axis, X Axis Alignment – Setting the X Axis Rollers, X Axis Alignment – X Axis Lead Screw Nut Alignment, X Axis Alignment – Inspecting the X Axis Stepper Motor, X Axis Alignment – Reassembling the X Axis, X Axis Alignment – Final Adjustment and Testing. Do you recommend to subtract the distance between the probe and the extruder nozzle and modify the Z_SAFE_HOMING_X_POINT value accordingly or there is a smarter way to input that distance in an initialization stage of the code? A few prerequisites are needed to use sensorless homing: 1. One way that you can increase your max material thickness that you can cut through is using double sided machining. Whenever you open UCCNC, the very first movement you should make with your machine is “Home All”. C++20 behaviour breaking existing code with equality operator? So, what about homing? 2. Example 1: New Z Value is 113.66mm (4.47″), if you divide that number in half, that would mean you can use a piece of material that is 56.83mm (2.23″) thick and the tool would have to stick out 56.83mm (2.23″) as well. A surfacing bit is perfect for this, especially with machines where the spoil board is physically attached to the machine – you might want to prolong the use of it for as long as you can before replacing. This is because UCCNC will only accept millimeters as a parameter! This will force windows to save the file as a .txt, which can be easily recognized and opened. SPI / UART interface of the TMCxxxx wired to MCU (stand-alone mode does not work) 3. Finally, under [Mesh Leveling], I want to think that you need to comment out [#define Z_SAFE_HOMING]. September 2016 in Motor Control. Ouch!!! 3D Printing Stack Exchange is a question and answer site for 3D printing enthusiasts. This would mean you can have a material thickness of 75.33mm (2.96″), or two-thirds and using a cutter with a length of 38mm (1.49″) you can cut one side of the project and then flip it over and cut the other side – so you are using a shorter cutter to cut through a thicker material by cutting each side. Auto Homing showing failing Z-homing. Asking for help, clarification, or responding to other answers. G29 goes to all three locations (3 point leveling set) at each one it drops the bed maybe by the Z_HOMING_HEIGHT then moves to the next location, never homing. The following represents the spindle and spindle nut stick out you get on a D-Series machine with the HF-500 and MM-1000 spindles, HF-500: 31mm (1.22″)MM-1000: 38.6mm (1.52″)MM-1000 (with single spacer): 32.56mm (1.28″)MM-1000 (with dual spacers): 26.34mm (1.04″). This command sets the z-axis height when the bed is moved completely away from the nozzle (that is, it is at the bottom of the printer and has triggered the Z maximum endstop). and another thing is eeprom not save when i turn off the printer an next day i try to use the same z offset its disappear This comment has been minimized. This is known as a reference movement for the machine. For example…. Turn the power key switch to the ON position. I believe at the time their thinking was the Z end stop was for homing and Z probe is for bed leveling “after” it has been homed. In my case origin point is correcty set. If your machine is stopping short of the full length of travel and you aren’t noticing any binding, make sure to “Home All” and try running again. The homing process has noticeably changed from old Marlin, so perhaps the new routine has an issue? Why does Steven Pinker say that “can’t” + “any” is just as much of a double-negative as “can’t” + “no” is in “I can’t get no/any satisfaction”? 1/10th the size designed) you are most likely using the incorrect post processor. Typical delivery times for a pre-built machine is up to 30 days. Did I make a mistake in being too honest in the PhD interview? Thanks for contributing an answer to 3D Printing Stack Exchange! homing synonyms, homing pronunciation, homing translation, English dictionary definition of homing. Yes, either of the preheat homing option let you specify the Z homing XY location,you can set the preheat temp to 0 to disable the heating part. It worked perfectly. http://www.cncdrive.com/UCCNC/download_UCCNC.php, https://stepcraft.us/product/deskproto-multi-axis-hobby-license-non-commercial-use-only/, Vectric Software (Cut 2D, Cut 3D, V Carve), https://www.stepcraft.us/shop?search=performance, Design your project in a CAD/Drawing program, Use a CAM program to assign tools and tool paths to the project. Z axis homing inconsistent on UM2: workaround and patch I mostly measure the thickness of the prime frame that prints before the print starts with a digital caliper. Are those Jesus' half brothers mentioned in Acts 1:14? Do rockets leave launch pad at full thrust? 20mm above work piece to focus positioning laser beam clearly. As a side-effect, X and Y homing are required before Z homing. I have rebuilt a 1st gen cube 3d printer to use more conventional hardware and have 1 thing left that is a bit of a annoyance but not sure how to go about fixing this. In order to use the 4th Axis, you need to have a CAM program that will support creation of the tool path for the 4th axis. If your laser positioning guide wont turn on after following this procedure please contact our support team and they can guide you on how to fix this issue. Maybe I´m just to blind to see, but I´m missing the some features in 14.03... After pressing the print button there was usually a seperate window ( at least in 14.01) with some temperature settings and the possibility for jogging all axis and do homing. The following video will show you how to level your heated bed for your 3D printer…. Consult your machine’s manufacturer for assistance with proper speeds and feeds for surfacing bits. For more information on the performance kits, please visit: https://www.stepcraft.us/shop?search=performance. Distance from z to z stop and distance from bed surface to z stop. Is it my fitness level or my single-speed bicycle? The purpose of any CAM program is to take your design file and turn it into G-Code by assigning tool paths to your project and outputting it in a format that a CNC machine can understand. In the ATZ screen what is the XY position, safe Z distance and Z feed rate set at? Can an electron and a proton be artificially or naturally merged to form a neutron? Machines need to know where their origin is located for all of its axes. Define homing. Homing after it falls no longer raises z axis, presumably because it assumes z axis doesn't fall when powered off. If you homed the Z-Axis in a location where the Z-Probe would miss the bed, really bad things happened. I'll bet you are wondering, what about the z-axis... Should it be in the upper most position, or at the surface of the work piece. Fusion 360 is a very powerful program that can greatly expand the capabilities of what you can do with a STEPCRAFT (or any CNC for that matter). This means that you can design in inches, millimeters or anything you choose, and the post processor will always do the proper conversions for you. If you have not been able to address the problem please update your question. Homing sequence: You can execute homing procedure via Machine menu Machine/Home or left toolbar button: When Homing is executed, homing sequence(as set above – see screenshots) will be: Z axis will be referenced first. If you are looking to engrave .005″ into a piece of metal and your bed is off by a couple thousandths from one side to the other or front to back, then the thickness of your engraved lines will vary. Making statements based on opinion; back them up with references or personal experience. If stepper drivers time out, X and Y homing will be required again. A surfacing bit typically has a larger than normal cutting diameter (1 to 3 inches) and are used to flatten or level uneven surfaces on your project material. It probably would be better stated as a carriage mounted probe. Axis will move in positive direction until Z axis limit switch is activated. Without this reference movement, the machine has no idea where it is along its axis and may not travel the full length back and forth. If you enabled Z_SAFE_HOMING, then automatically the printer homes Z at the middle of the build plate, if the bed size dimensions are correctly defined (in your case X_BED_SIZE and X_BED_SIZE should be defined as 300). In Configuration.h you can find: This installer will automatically install the most up to date profiles and macros. Recommendations. If so, has the answer below led you to the solution? Now depending on what you intend to do, you can use this new value to plan your project. Z Safe Homing prevents Z from homing when the probe (or nozzle) is outside bed area by moving to a defined XY point (by default, the middle of the bed) before Z Homing when homing all axes with G28. Happy printing! What Constellation Is This? G1 Z3 F5000: Raises the Z position up 3 mm relative to where it was (G1 tells the machine to move, Z3 tells it how much to move and along which axis, F5000 is the speed of movement) G92 Z0.3: Treats the current position as Z = 0.3 (applying an offset of -0.3 and creating a sort of false home for the Z-axis).
