For the laser, I am pretty much exclusively using Lightburn, so I can probably just make a macro in there to home and focus the laser all in one command. Z-probe height (Probe commands:): Depending on the code there, you need to add something like a "G92 Zxxx;" (xxx is the mm value) and if want some rectraction after it: "G0 Zxxx F100" Safe home (Safe position commands:) Nov 14, 2021 · The reason for this is that your workpiece is thick enough that 10mm (0. 3937") below Z home (top of Z travel) is in contact with the work. This will set the work offsets, usually for G54 (the default) co-ordinate system. offset (G92), Tool Length Offset (TLO) & Probing cycle (PRB). I “think” z home is really intended for end stops, so the touch plate probably makes more sense for probing, and I could set offset (G92), Tool Length Offset (TLO) & Probing cycle (PRB). If your machine is in fact homing Z then you have a few options: recompile the kernel to set Z position after homing; configure a work offset for Z to adjust „Z Offset“ und „Z Step per Pass“. The core of the whole thing is the command G38 (probing) in grbl or g-code (explanation see here). your spindle will rapid to this position and from there start the seek process; You also need to change the G28 Offset, to the difference between your shortest and longest tool. So, Grbl is trying to home Z, when you don't have a Z-axis on your laser. May 11, 2021 · Does anyone have a good explanation of how the Z axis Offset works? If I my first layer is a fill layer and I have a Z axis offset of 2mm does the the Z axis move down (or up?) 2mm from where I set it before sending the file to the laser? If the next layer has a Z Axis Offset of 1mm does that move it down 1mm from where the last offset left it (i. Z Offset (Z Home Offset) – What Is the Difference? Due to both their names and their purposes being extremely similar, the Z probe offset and the Z home offset parameters are frequently mixed up, creating discrepancies in the configuration that usually end up with failed prints or errors from the 3D printer. h on how to alter your homing cycle.

By default, grbl detects a contact to ground on Pin A5, which means, the cutter / probing-tool is connected to ground (because it is perhaps already connected to ground via the spindle and support) and the touch-plate is connected to Pin A5. If you enable a workspace offset, you will also need to make GRBL report its location relative to this shifted origin, instead of in "machine space", by setting $10=0. 3 coordinate system to the location of your Tool Length Sensor (the physical location of your TLS on the wasteboard). A negative workspace system looks like this: In this image, the origin is at the rear 3. 3. Example - [G0 G54 G17 G21 G90 G94 M0 M5 M9 T0 S0. . 0] Jan 23, 2024 · When homing, does Z-axis also home?
