@Phaedrux thanks for the pointers - my config.g file is in my initial post. I am using the DWC I was just referencing the RRF Config as the point where I started. Any suggestions you can provide based on the numbers I am currently using would be great! Thanks again.

Posting the config.g below as well:

@taconite Thanks for the reply. I just reviewed your thread and I would say that the answer 'almost' has to lie within the motor/stepper/interpolation values. Its hard for me to believe we would be reproducing the same issues when I am using a Cartesian printer, different lead screws, etc etc. I think the commonality lies within the stepper settings.

I have been trying to use the RepRap Config tool to generate different combinations and so far the pictures above are as close as I've gotten - which I don't believe is a very good print.

The 'general' settings are:

Unfortunately I am not sure what the right combination is - and there are way to many variables to just guess and test. What I do know as far as my setup is that I am using 0.9 degree motors for all drives. For the Z drive my lead screws have 8mm pitch. I have tried x16(on), x128(on), x256(on)...etc.

But I'm at a loss so any suggestions would be great.

Hello All - I am experiencing a print issue with my new setup that I have not run across before and I am having issues resolving it. If anyone might have encountered this before could you please let me know what the issue might be. I have a couple of pictures and my config.g setup, and the g-code for the cube (using Simplify slicer) below.

*Additional useful information - using Duet3
Board: Duet 3 MB6HC (MB6HC)
DSF Version: 1.2.4.0
Firmware: RepRapFirmware for Duet 3 MB6HC v0.6 or 1.0 3.0 (2020-01-03b3)

All of the stepper motors (including extruder) have a motor step angle of 0.9.
Duel Z-Axis motors in parallel.*

Thanks in advance for the assistance.

PS - This is obviously zoomed in quite a bit so for reference the cube is 20mm x 20mm

Bloody hell, I know I was in the right place when I started but I've pulled it out so many times rewiring I must have inadvertently put it back in the wrong place. With the lines switched up (per your earlier comment) and the plug in the right place - we're working now! Thank you, thank you for your help!

@PaulHew no I am not using I1 as my understanding was this was no longer needed. I agree with your assessment of the deploy/retract commands and I also read that as of RRF3 the M401/402 could also be used. For all of them I am entering them manually bc I don’t want to home when I cannot get the BLTouch to deploy manually.

More information - I'm not sure if it is helpful or not but I thought I'd also include the diag (M122) that I just ran in case it provides any clues/info.

@PaulHew thank you for the suggestion, I just tried it and still no reaction from either the deploy or retract commands.

PS. - I have tried both the M401/M402 commands as well as the commands deploy/retract commands (M280 P0 S10/M280 P0 S90)

Thanks again

Hello All - Any help would be greatly appreicated.!!

I am using a BLTouch from a prior application that was working when it was removed. It is the Version2 on the most recent firmware. I've been setting up a Duet3 + Expansion Board and I have most things working but I cannot get the BLTouch to deploy. When I power up the system the BLTouch successfully completes its self-test and then remains in a state of pin retracted and a solid red light. On the Duet3 board I have the BLTouch wired to IO_7 per the instructions on the Duet Website.

Pin 1 - 3.3v - Empty
Pin 2 - In - White
Pin 3 - Ground (Combined Black & Brown)
Pin 4 - Control - Yellow
Pin 5 - 5v - Red

*I have wired and rewired everything a number of times to ensure the connectors/connections were not the issue. I guess there is some chance that wiring connections could be the issue but it is highly unlikely.

*Pictures attached at bottom

As far as my configuration - I have tried a number of combinations to no avail. I am using the RRF Config tool as my starting point to generate the baseline code. I've included the code sections below but as far as the BLTouch here is what I have tried. For each the initial result varies - but the consistency between all of the combinations is that none of them react to the manual deploy/retract statements.

Input Pin - IO_7_IN / PWM Control Channel - IO_7_OUT - BLTouch self test is successful and then this gives the initial value of 1000 and on the machine specific settings the endstop shows as triggered. If I manually pull the pin on the BLTouch the red light goes off - but there is no change in the interface and no commands change the state of the BLTouch.

Input Pin - IO_7_IN (Inverted) / PWM Control Channel - IO_7_OUT - BLTouch self test is successful and then this gives the initial value of NA/0 and on the machine specific settings the endstop shows as 'not' triggered. If I manually pull the pin on the BLTouch the red light goes off - but there is no change in the interface and no commands change the state of the BLTouch.

Input Pin - IO_7_IN (Inverted) / PWM Control Channel - IO_7_OUT (Inverted) - BLTouch self test is successful and then this gives the initial value of NA/0 and on the machine specific settings the endstop shows as 'not' triggered. If I manually pull the pin on the BLTouch the red light goes off - but there is no change in the interface and no commands change the state of the BLTouch.

The only other thing I would note is that I am running to drivers for my two Z axis and the extruder driver off of the main board and then I have the x/y drivers and their endstops on the expansion board. I do not think this should matter - but who knows.

Of course the G-Code is slightly different for each of these options but I'm only providing one version below - just to give a general idea of the overall setup.
