@dc42 Unfortunately I had to extend and run this cable through my system that took a few hours to do, and I did not connect the unused wires along with both ends needed flipped. I was hopping to take the ends apart and reverse, but I broke to many parts. Will have to order some ends, but the Accelerometer was found and I ran my first test late last night. So good news no fried parts! Thanks for your help

@jay_s_uk Looks indeed promising!

I'll dig into it! Thanks!

mmm, now it stays -1% to max 1% ??

Duet3D laser filament monitor v1 on pin xstop, disabled, allow 10% to 120%, check printing moves every 3.0mm, calibration factor 1.000, version 1, measured min -1% avg 0% max 1% over 14966.6mm

@ZPomeroy said in MPCNC Endstop G28 Issue:

G1 H1 Z-125 F360 ; move Z down stopping at the endstopG90 ; absolute positioningG92 Z0 ; set Z position to axis minimum (you may want to adjust this)

In your homeall you're doing a homing move as if you have an endstop to home to, but you don't have a z endstop defined in config.g

How do you intend to home your Z axis?

Right now you have a manual probe defined, so it would prompt you to manually jog the axis to touch the Z0 point. To use that you would need to modify your homez and homeall and change these lines

G1 H1 Z-125 F360 ; move Z down stopping at the endstop G90 ; absolute positioning G92 Z0 ; set Z position to axis minimum (you may want to adjust this)

To simply G30 so that it would call the probe and prompt you to home Z manually.

@ZPomeroy said in MPCNC Endstop G28 Issue:

Sometimes the motors will skip and start making a horrible noise when the endstops should have been triggered.

Can you give me detail about this? Maybe a video showing what is happening?

Do it happen every time? Randomly? Does the axis move normally otherwise?

Good morning @dc42,

After receiving your response and gaining a better understanding of the workings of Heater3, I have decided to remove this section from my circuit. Since Heater3 does not function as GND, I deemed it unnecessary. However, the outcome remains unchanged. Based on its behavior, when I activate and deactivate Heater3, the brightness of my LEDs simply diminishes. I'm beginning to think that either the 3V is insufficient, or the 0V doesn't manage to turn off my transistor.

I look forward to your response.

@amcdave the RPi might have been used to control the Duet with Octoprint or Repetier Host. You don’t really need it if you connect the Duet to your network.

@Toastinator Hello, I tried to install ESS ProTuner software from that link but i think it's deleted from OneDrive. Could you tell me where can I find this software because I checked everywhere but i

@axiom the over temperature message is specific to that driver. Does it feel hot? You can get spurious messages if the SPI bus (used to communicate with drivers to set their configuration) is damaged, or a damaged driver is sending garbled message, but this seems pretty consistent that driver 4 (E2 on a Duet 2) is damaged. You can disable the driver and messages in config.g using

M569 P4 R-1

This may be of interest to anyone looking at this in more detail as it allows examination of bgcode files.

https://github.com/ellensp/bgcodewalk/blob/main/README.md

The example given seems to show Heatshrink compression being used along with Meatpack, both of which I think are designed to use a relatively small amount of memory to decode.

@sbNielsen

Always glad to help when I can.

@gringo glad to help you

@gallaghersart of you mean a 120R resistor to terminate the CAN bus, 1/4W is more than adequate.

I get kicked out of the house at 10pm by my parents.

Ouch !!!

Heh, yes, it is working as expected. I did a full reload of everything and now everything is working.

I do like the resident bootloader (permanent) that resides in the Mini5+, reminds me of a project that I did 15 years ago. Nice work!

@cosmowave Thanks for that.

@dc42 So AC SSRs connected to the 3HC PWM outputs? How were the segments controlled? Was it automatic or do you have to manually choose what segments to heat?

Thanks much.

Now my model of the E3D MotionSystem/Tool Changer, as modified and built by me, is complete.

@fcwilt https://www.duet3d.com/duet3magneticencoder

How neat. I didn't know they made those.

So either add a spacer or buy a longer magnet.

If you need to buy a longer magnet you should be able to find a site like this that has all sorts:

K&J Magnetics
