I don’t know about any guides yet, but have a read through these. Pay special attention to the ‘gotcha’ about using the z min endstop. You can use it, but you have to tell marlin to define a pin, then set that pin to the z endstop. If you just tell it to use the z endstop, it doesn’t work for xy probing. At least that’s how it was 3 months ago or so. Not sure if that’s a bug or a feature. It should make more sense by the time you’re done reading.
I’ve been playing around with making an aluminum Turners Cube on the MPCNC and found myself wanting a way to easily set the origin of the machine to the corner of the work. For this project I’m mounting the workpiece in a 3 inch vise . I replaced the metal vise jaws with 3d printed ones to avoid marring the aluminum. After squaring the stock, the Turners Cube requires making the same cut on all 6 sides of the cube. I realize that I could have mounted a stop on the vise to get repeatable clamping …
I’ve been playing around with the dual end stop firmware and a Z touch plate. I can home Z with the touch plate but it does not trigger when using G38.2
I’ve defined FIX_MOUNTED_PROBE and G38_PROBE_TARGET
I’m using Marlin-MPCNC_Ramps_T8_16T_LCD_32step_DualEndstop in version 302 as of today, had the same issue in 301
Any ideas what I can try?
Thanks
Has anyone tried implementing this?
I’m using Home’Z’(G28 I think) with a touch plate but I want to touch off the sides of a corner touch plate as well to set all 3 axis of my workpiece origin.
What do I need to do ?
It seems that marlin has an issue with negative X or Y probing. For Z all is ok.
As example:
The sequence
G91
G38.3 X10
G90
Works properly.
But the sequence
G91
G38.3 X-10
G90
In most cases didn’t make second touch. Stop somewhere in the middle in a random position. Sometime it stops even without making first touch.
Same behavior for Y.
Disabling software endstops doesn’t help.
