OK. Thank you

Was looking at the pendant project. As I understand, it sends gcode via serial. So, is it possible to send whatever gcode I want, like call a macro directly by pressing a button?

My bad, I didn't expect g92 set position AND flag as homed. Thx for pointing me my mistake

@droftarts said in Double motor axis homing question:

I don't think the axis is marked as homed.

Here is the problem, it's homed. I'tried again with my Z axis (1 motor, short stroke), the same

So I manage to check with conditionnal and it works. But, there is a major issue in firmware I discovered during my test. Its a critical safety bug in my opinion. Firmware check during homing move if sensor is hit, but doesn't care if not. If you don't hit sensor, the move continue to distance you specify, stop and do the second pass as well without controlling after complete distance. Ok, I can test it with conditionnal, but I really don't understand this kind of homing procedure inside a so good board.

I should give it à try. Thx

OK. Maybe I should post a request on firmware github. In my opinion, it's a real issue with 2 motors axis.

Hi, I'm configuring a duet 3 6hc with raspi4 as my cnc controller.
The cnc is cartesian with 1 X, 2 Y and 1 Z.
Everything seams good but I think I forgot something in my config or/and home y file.
Actually, I can home all together or individually.
My question is about homing procedure.
I've got switch with active high for each motor, when homing if a switch or his wire is broken, the machine think it's at endstop and then revese for doing second pass, wich is normal. But what about my double Y, the motor with switch broken stop and wait for the second switch to be eaten. How can I tell the duet to travel to the next switch within 20mm max, is there a way to do that?

I inverted gpio pins 2, 4 and 6 under the pi board (so no more in the ribbon cable) and solder 5v directly on it. Works like I wanted. Thx

I already have à 5v psu just for that. Was hoping not to have to do my own ribbon cable(I don't want to use the usb c power port on pi). Thx for the help

I mean I don't want to unplug and plug my pi each start

OK, not what I expected.So, is it possible to
wake up pi with pson pin?

Hi, I'm trying to wire à duet3 6hc rev 1.02 with à pi4. What I did:
-removed sd card from duet
-Wired 24vdc psu to duet power in
-wired 5vdc psu to duet ext 5v (+5 and gnd, no pson)
-put a 2 way jumper between ext 5v and ext 5v sel
-User original 26 to 40 pin ribbon from duet
When Turn on, duet seem's to start correctly ( 4 led on + statues led blinking) but no power to pi (I tried pi 3 and pi 4, no led activity at all)
What am I missing?

@Phaedrux OK tanks

Hi,

I made a CNC router last year with an arduino mega2560 with ramps, external drivers, spindle with VFD. Mechanical parts are good (aluminium strut profile, linear rails, ball screws) but arduino with ramps seems not to be well shielded and I had a lot EMI problems (end stop false positives). As I have a duet2 on a 3D printer I made wich I love to use, I deceide to ask Santa to send me a duet3 6hc, he did it !
I'm now drawing an enclosure for it and have some questions without answers, so here I am:
I want to use the duet with a raspberry attached, pi will be use as human interface (maybe with plugins) with just mouse, keyboard and screen, nothing more. I now have a raspberry pi 3B+. Is there any interest to buy a pi4 when it will be avaible?
For now, with pi3, can I use the duet power via the ribbon cable without external PSU?
What about pi4 (if needed) without external PSU and same simple use?

Thx in advance

Hi,
How can I mark this post as "solved"?

I received the new thermistor. Everything seem's to be ok now. Thanks to everyone who tried to help me!

I removed the connectors and soldered, exact same problem. I will now wait untill E3D open and send a new one

So, I tried hook up ohm meter on thermistor cable (board side) after my extruder reach 200°C, resistance rise linearly and suddenly drop too. I did the same without the cable (thermistor side), exact same result. I think my thermistor is dead. (please, ask if you don't understand my poor english )
