@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.
https://www.thingiverse.com/thing:2476165

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.
Jake

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.

Hello all,
I've got a delta with UVW and they are not homing correctly. I've had it homing correctly when using stall detection, but it was not as reliable as I'd have liked so I installed optical switches. I've setup the optical endstops in the config.g and updated the homeu homev homew and homeall to behave exactly as the delta towers home but for some reason it sets some random home as U=837.33 V=1024.38 and W=677.77. I'm pretty lost as to why this would happen. 0 should be the max and -180mm is the min. Obviously bad things happen when I ask for a U toolchange. Any ideas?

homeu.g
; Homing file for the U axis of the Toolchanger
M400 ; make sure everything has stopped
G91 ; Use relative positioning
M913 U100 ; Power U axis
G1 S1 U200 F5000 ; Up to find home
G90 ; Back to absolute
M400 ; Make sure everything has stopped
M913 U50 ; Keep the motor cool

Hello All,
How exactly are machine coordinates handled for a delta with auto calibration? Does the probing routine change G53 or does it apply those offsets to a G54/55/etc? I've got some things that need happen in machine coordinates(that never change) at the top of a delta and the operation keeps crashing when I update say the babystepping or the tool length offsets. Any wisdom would be very appreciated. Thanks.
Jake

You're the man David!

Is It possible while using a Duetwifi and Duex5 to get an 11th stepper drive hooked up externally? If so what where would I hook up the step direction enable? I need 11 steppers for the build I have envisioned. Thank you.
Jake

This is beautiful David! Very nice feature to round out the functionality of your boards.

I would also love to know when the filament monitor will be ready for sale. I'm in need of quite a few.
Jake

I was running the 1.19Beta11. Updated to the newest release and everything works It's just like you to solve problems I didn't even know I had, lol! Thank you so much David! The features you're working on are amazing!!!

Good evening forum,
I've got a Delta printer of my own design that uses the traditional towers but also has another three axis(used for another purpose) that need to home. I'm having a heck of a time getting even just one extra axis to execute G28 correctly. I keep getting "Attempt to move the head of a delta printer before homing the towers" I've added the U axis just like in the https://duet3d.com/wiki/Configuring_multiple_independent_X-carriages_on_a_Cartesian_printer with M574 U2 P1(Endstop active high at top). I've also mapped the motor drive and direction with M584 and M569 respectively. M208 U-170 S1 and M208 U0 S0 for min and max travel. I've assigned acceleration, steps/mm, current, and jerk values.
My homedelta.g file is as follows:
G91 ;Relative positioning
G1 S1 X1000 Y1000 Z1000 F3500 ;Move all carriages up 700mm, stopping at the endstops
G1 S2 X-3 Y-3 Z-3 ;Move all carriages down 3mm
G1 S1 X6 Y6 Z6 F250 ;Move carriages slowly up 6mm, stopping at the endstops
G1 S1 U310 ;Home U axis up
G1 S1 U-3 ;Back off U axis 3mm
G1 S1 U6 ;Home U slowly up 6mm, stopping at the endstop
G1 Z-5 F2000 ;Down a few mm so that we can centre the head
G90 ;Back to absolute positioning

Also the homeu.g file:
; Homing file for the U axis of the
G91 ;Use relative positioning
G1 S1 U310 F500 ;Home U axis up, stopping at the endstop
G1 S2 U-3 ;Down 3mm
G1 S1U6 F250 ;Home U slowly up 6mm, stopping at the endstop
G90 ;Back to absolute positioning

I'm a little lost as to how to get this guy up and running and any help would be very appreciated. I'm hoping this isn't an issue with firmware and g28 commands for delta configurations. Thanks so much.
Jake
