So you're driving the X axis off of tool boards? And the tool boards are in the heated enclosure? How hot does the enclosure get?

The toolboards are located in a separate enclosure with a radiation shield between. None of the boards are exposed to extreme temperatures.

@Phaedrux said in Jerk Control M566:

The tool boards can handle quite a bit, but still, probably should be running the X axis off the mainboard. I'm not sure I follow the reasoning though, the PT100 could still be wired back to the mainboard with the extruders on the tool boards.

The x and u-axes are driven by the toolboards because the extruder drives had to move from toolboard to the main board per the bullet point criteria from this section. I responded to that criteria by moving the drives around ending up with the IDEX motors on toolboards.

Which particular constraint prevented you from using the tool boards to drive the extruders?

Below, I bolded part of a quote from a previous thread. At the time my firmware was not up to date which would have allowed me to connect my IR Filament monitoring to a toolboard per this criteria.

from the link:

A heater on an expansion or tool board can only be controlled by a temperature sensor on the same expansion board

I am measuring my hot ends with pt100 sensors on a temperature daughterboard. I feel as though as I will have to swap around my arrangement, perhaps swap my extruder driver to the main board and run my two hot-end carriages (they move independently along the x-axis). I also have IR filament monitors I need to setup.

Currently:
Driver 0 -- X (left carriage/X axis)
Driver 1 -- X (right carriage/U axis)
Driver 2 -- Y1 motor
Driver 3 -- Y2 motor
Driver 4 -- Z1 motor
Driver 5 -- Z2 motor
Toolboard 20 Driver 0 -- E0
Toolboard 21 Driver 0 -- E1
out1 -- signal to bed idec relay
out2 -- signal to chamber idec relay
temp0 -- Bed thermistor
temp1 -- Chamber thermistor

Revisions implemented:
Driver 0 -- E0
Driver 1 -- E1
out1 -- left hot end
out2 -- right hot end
Driver 20.0 -- X (left carriage)
Driver 21.0 -- X (right carriage)
20.out0 -- signal to bed idec relay
21.out0 -- signal to chamber idec relay
20.temp0 -- bed thermistor
21.temp0 -- chamber thermistor

this way my extruder motors are monitored by filament monitors and pt100 on the same board. And my heaters are all being monitored by sensors on the same address.

I have updated the firmware for the MB and TB's to the recent release about a week ago, that said I can rewire somethings and see what results it'll produce. I am still waiting to hear back from the machine's designer to ID the motors so that I can specify current ratings in the config.

The support team over at AON have been really delaying getting back to me. However, my boss went ahead and ordered a duet EX3HC. The results were excellent right out of the gate. All of the layer shifted existed on the x-axis which at the time was powered by low current channels . At any rate, I have new issues to uncover and fix but for now I will call this a victory. I will start a new thread in regards to complications I face with the expansion board.

Thanks for everyones help and suggestions, ultimately it led to discovering a trivial mistake.
