Help configuring vers 3.3

jmorganmkm

Hello everyone,
I recently acquired an older model MPCNC from a friend and foolishly updated the firmware and lost everything.
I have zero experience with 3d printing but my day job is programming and setting up HAAS and Fanuc cnc milling machines for an aerospace company. Somehow i figured out how to configure the drive and endstops for the x ( 0 and 3 ) and the y (1 and 4). Everything homes correctly but when i try to run a simple program the router doesn't read the x and y correctly and goes up and down on the z. any help is appreciated. I found doing the research to be extremely difficult trying to sort through all the versions so just posting current config.g and homeall files would be extremly helpful.

Do you mean that X and Y don't move, but Z does? Or something else?

After you run homing and before you run your file, does Duet Web Control show X, Y and Z as all homed (axis buttons blue instead of orange)?

Please post your homeall.g file.

I think the machine homes correctly and I am able to jog the machine in the correct axis and distance. The second file i uploaded was the start of a snowflake engrave but instead of lowering z to -.04 and moving the xy it instead lowers z to -.04 and than raises it again, moves to another position and drops z again, raises it and moves xy.
My next idea is to put it into cartesian mode but i thought that was default. here is my homeall

@jmorganmkm have you confirmed that you are running firmware 3.3 and that it is in CNC mode? Send M115 to check the firmware version, and send M450 to check the printer mode.

Your file sends X and Y coordinates without a previous G1 on the same line. That's supported by RRF in CNC mode but not in FDM mode.

I just confirmed it is in cnc mode and 3.3.
I'm going to try adding more g1's to the program and see what happens

@jmorganmkm I found this item in the bug fix list in version 3.4.0 at https://github.com/Duet3D/RepRapFirmware/wiki/Changelog-RRF-3.x#reprapfirmware-340 (search for CNC to find it):

In CNC and laser mode it is permitted to omit G0/G1 at the start of a line of GCode and just provide parameters, provided that the previous command was G0 or G1. However, only parameter letters that were present in that previous G0/G1 command were recognised.

So this is a bug in 3.3 which is fixed in 3.4.
