hello all 
I'm planning to build a fabric laser cutting machine
but as I have not enough space (and money) for buying a real machine and as I need to cut very long part, I've come up with an idea 
I will keep fabric on 2 rollers (1.5 m long) passing from one side on another from a cutting line (Y axis) with a moving laser diode head (X axis) 
if it was so simple I would use a cheap 3D printer / cn machin controler but whatbrings me here is that I need a closed loop position controller 
idea is that roller will be motorised by 2 motors ( left and right ) and will only working by pulling on fabric ( meaning that 2 motors will work in +Y and 2 in -Y) but I can't rely only on steps on motor to move accurately the fabric as depending on roller fabric diameter changing the distance of fabric moving on cutting line 

on the other hand fabric can also moves on X axis when rolling and unrolling and objective is to use differential of both right and left motors to correct position 
in my idea the close loop in postion control can be supporte by an optical mouse sensor that can track X and Y moves and I can put 2 on each side right and left 
my question is: is linux cnc can be configured to adapt of this strange machine ? 
 

sweet no worries!

Delete the red potion and make sure the lines above and below it are there still for the manual tool change.

need some lines in your main hal file also, check the docs it spells it out very clearly in the machine config setup docs. step 5.

Hello All!

We are preparing to merge a BIG Probe basic update. it will require some config setting updates and some new folders be added.  I have added a new "Update Release Notes" section to the docs page which should be very helpful going forward for when we have updates release.  please feel free to have a look and give feedback!

My manual tool changing does the Probe Basic. 
If in MDI I use "T2 M6 G43" , the line stays active with the play icon, but never ends.  The same issue in NC files.

Nothing happens, no pop-up, etc
