A Bit of an update.

After getting my mate to spend way to much time on it troubleshooting the problematic Z axis issue, he decided to make the nema 23s just motors instead of integrated steppers. Not long after I had a fully functioning Z axis. The X and Y axes are still the integrated stepper and work well.

Printer is calibrated on the XYZ axes. Tested the extruder side as well all functioning. Only thing really left to do is put the bondtech on it and the usual bed calibrations etc. Then we are off and printing.

Thanks for all the assistance in getting this up and running.

@bearer Just went through that thread, thanks for the great response.

@bearer
Thanks for the reply. You pretty much answered my question. I will use the duet 2 for now and upgrade it to a duet 3 when the necessary duet 3 products are available. By chance you wouldn't be able to hazard a time frame on when something like that would be available for example 6,12,24 month timeframe?

Hi Guys,

I am most of the way through a pretty large printer design.
I am now looking at the wiring side of it.

The machine is using ballscrews on all axes with 2 servos on the z axis and 1 each for the X and Y axis. The servos are the Teknic Clearpath Servos.
I will be powering the servos through the Teknic IDC power supplies I looked at some of the comments made by @Edkirk on what he did.

https://forum.duet3d.com/topic/8876/clearpath-servomotor-50nm-suggestion. In this build, a duet 2 was used in conjunction with the expansion board. On the expansion board, the I/O is six pin which matches the clear path setup and I know which way to wire it for that.
The issue is I would like to attempt to use the RaiseCloud solution from Raise3d, I am already very familiar with their environment and I quite like it. There is now a plug in for an RPI that works and I was looking at attempting to integrate this with the duet3, where I am becoming stuck is the wiring of the servos see the image below of the 8 pin wiring of the servo.

The image below is from @Edkirk wiring setup of his clear path servo to the duet 2 expansion board.

The issue that I am having at the moment, is how would this wire to the duet 3 expansion board? I cant use the duet 2 expansion board as it has a 50 pin cable where the duet 3 pin header is utilised by the SBC.
The Expansion board for the duet3 has 5 pins which is one less than the duet 2 expansion, I am just after a bit of guidance on where to get going. Any help would be appreciated and if more information is required, please let me know.

Thanks for your time.

Some good news but also some bad news.

Everything is working so to speak. Ran the first print, and I am getting layer shift on the X and Y axis on every layer. Different prints different direction.
I am using Ideamaker as the slicer, I do not think this is the issue, but it is information.

The X and Y axis are still controlled by the integrated steppers.
As the print continues it gets progressively worse.

See below for the config file.

@nhof
Thanks for the advice. I will have a look and test to see how that goes.

This Axis is functioning correctly, so I thought I would also post this as well just to provide further information.

@Dougal1957 , @Phaedrux
Will post the data below,

We set it to 0 after the first time we were setting the other axes it tried to drive it down. It is only at 0 till we have it sorted.
