I like soft limits!  Soft Limits does not like my 4th axis (the extruder on my 3d printer) and often during a print I exceed the limits (not sure how cause I have the limits set to 10M but it still trips) and program stops running.  Is it possible to disable soft limits for just 1 axis?  Thanks


I'm running G-Code for a 3D printer and there are multiple G92 A0 commands written in the code to reset Extruder position.  G92 A0 does work as expected when runing the program However, when I stop or pause & jog machine and try to resume or do a "run from here", prep move cause A axis to do weird things (i.e. start counting up/DRO is actually showing incremental numbers whereas XYZ do not.

I have tried substituting a G92.1 A0 command in the GCode and this does prevent the A axis from counting up and does leave the A axis ready to perform as expected upon RUN.  BUT then every subsequent G92.1 A0 command causes the extruder to physically wind back to 0 instead of just setting the DRO to Zero.

Haa anyone else figured out a way to deal with this issue?

Thanks in advance for any replies!!!


I am trying to get User Numerical Input DRO data into my PLC (AutoDir P2K).  When using the TCP test Modbus screen I am able to read & Write data to the PLC so I know I've got a good connection.  I have succussfully been able to get data from the PLC to display on a MACH screen.  So far so good right?  Well I am stuck and getting data FROM MACH back to my PLC.  I'm pretty sure that I am messing something up in the Brains function.  But what?  There are only like 65K combinations and after trying about 10K of them, I thought I'd reach out.

Attached are screen shots of my current brain.  ANY Help or suggestions are really very much appreciated!  THANKS IN ADVANCE!
