@dc42 I've got a delta with end stops that are shy of ultimate height movement. There's a tool changer in the dead space of the delta and this way I can easy move in XY to get new tools. Any way the "target position outside machine limits" could controlled with the M208?

@dc42 The more I look at the schematics and work with the boards I realize that you're a badass wizard.

Thanks David!
Where do I sign up to be on that beta?!? In the mean time, do you happen to have a diagram of which wires on the ribbon are which signals?

I'm using a duet wifi with the signal expansion board. I've got 10 motors to drive and 5 of which are external close loop steppers.
I'm out of IO to control heaters, fans, air scrubber, led's and a couple other things so I'm curious which of the signals say heater 5-7 could be used to control things. Does that ribbon cable make use of all those signals for the external drives or can the cable be rewired to make use of plugged up signal? Or is there another board that somebody's working on to control 6 external drivers? Something like the Duex5 but for external drives?

Got the diagnostic from after it started again. I'll update the firmware. The "ground wire" is just a jumper between the Vin's? I'm thinking that Vin directly to ground will not turn out well. lol I'll keep you posted If the pausing is happening again. Thank you so much David for keeping up with this forum and solving so so many problems we didn't even know we had.

Hello All,
I'm having one heck of a time troubleshooting a problem. The printer will very randomly pause durring the print. It seems as if the gcode buffer is only down to a couple of lines and then it sits idle for a 2-30 seconds before continuing to the next commanded location. The gcode monitor shows a ton of motor phase disconnections for all phases of a bunch of motors. I'm running 2A Nema17 steppers at 1A for noise. The problem is that I can print the exact same part and one time it will come out perfectly and the next it will f-up.
Also I should mention that when I try to pause and home it doesn't recognize the endstops and smashes everything into everything.
Problem started when I upgraded to 2.02RC1 but it's still around with RC3.

Here's M122 diagnostic

Hello all,
Is there a way to monitor a 10K thermistor(Like this one over on amazon that is connected to the heatsink of a liquid cooling system and pause the machine if it reads above a certain temperature?

This is one I designed to be as minimal as possible.

Thank you so much. The G92 works in the homedelta.g file. I had tried that in the individual home files but it wouldn't hold the value when I used G28. Facepalm.
David, your responsiveness to issues and helpfulness on the forum is unparalleled. Thank you.

Hi David,
I can't post any photos just yet but the UVW are all belt driven linear axis. I can message a direct photo to you David if that would help with debug. All three UVW are identical with home switches at the top of the machine in the Z axis and the travel is in the negative direction by 180mm. I'm homing together but I've got U, V, and W home files separate as well. If I home seperately UVW from delta(comment out the homing sequence in homedelta.g) it shows -2 on all UVW right after the home but if I command a move to -180 it adds those weird values and crashes things.

Homedelta.g:

There's more about tool definitions but that hasn't effected anything.
