Complete sample config file for using Duex2 with 2 Z motors

Ignore for now. I will heat up the hot end and retest the movement.

I suggest you also use M122 to check that you have compatible versions of main and WiFi firmware, preferably both 1.21.

Hi and thanks for your input on checking the firmware versions. I had updated the Firmware version to 1.21, but not the Wifi Server and Web Interface.All three are now at version 1.21
I now have a working machine in that with only the DuetWifi connected, I can home all of my axes. I can't really do Z because it physically has two motors and I only connected 1 on the board just to make sure it would work. It does, and the directions are correct.
Today I will add the M584 code if I can understand the dozuki wiki. Not a board fault, or missing information, just me and my lack of the full knowledge of gcodes and their interaction / order.
thanks

Hi
I have added the M584 as I understand it.; Drives
M569 P0 S1 ; Drive 0 (X) goes forwards
M569 P1 S1 ; Drive 1 (Y) goes forwards
; M569 P2 S0 ; Drive 2 goes backwards original (Z) port on DuetWifi
M569 P3 S0 ; Drive 3 (E0)goes backwards
M569 P4 S0 ; Drive 4 (E1)goes backwards
M584 X0 Y1 Z5:6 E3:4 ; Z left is on Port 5 (Duex2 E2) and Z right is on Port 6 (Duex2 E3)
M350 X128 Y128 Z128 E16:16 I0 ; Configure microstepping without interpolation
M92 X750 Y400 Z364.446 E329.37:329.39 ; Set steps per mm
M566 X54000 Y54000 Z18000 E7200:7200 ; Set maximum instantaneous speed changes (mm/min)
M203 X60000 Y60000 Z16800 E72000:72000 ; Set maximum speeds (mm/min)
M201 X500 Y250 Z250 E250:250 ; Set accelerations (mm/s^2)
M906 X855 Y855 Z855 E855:855 I30 ; Set motor currents (mA) and motor idle factor in per cent
M84 S30 ; Set idle timeout
The comments will describe what I am trying to do. I would appreciate verification.
The example for the M671 is based on three leadscrews and I only have two.What I have measured is what the locations would be if the bed were large enough to cover the whole area. I will be getting a larger bed at some point, so I would like to confirm my understanding so that I will be comfortable making changes later.
M671 X-165:200 Y200:X330 is where the leadscrews would be if my bed was one large plane moving up and down on Z
Please confirm my M584 / M671 if there is enough information to do so.
Thanks

Hi:
I think I'm ok now.
X, Y and Z home successfully. Both Z motors appear to be in sync.
G32 returned an error which I saw flash by, but did not catch.
It appears as though all of my steps / mm settings on my drive motors are way off.
My question is if this is because I am now on 24V instead of 12V. Ie, is this expected?

Note:
My microstepping is shown above as 128. I have changed that back to the default of 16. Now my distances are correct.

This line is incorrect:
M671 X-165:200 Y200:X330
Did you mean M671 X-165:200 Y200:330 (I removed the second X)? That would mean your first leadscrew is at X-165 Y200 and the second is at X200 Y330. It's ok for the leadscrew coordinates to be a long way outside the bed.

Hi dc42
Yes, thankyou! That was a typing error on my part. I will correct that right now.
I'm actually having a different issue which I believe I have figure out, but don't know how to correct.
When I engage the bed heater, I have a 50% voltage drop. That might be what is causing my heater fault if I have the hot end heating and then try to heat the bed.
In researching heated beds, I see that they are not all created equal. I see different wiring connections at the bed for some, based on 12 or 24 volt connections. A common arrangement is 3 terminals, where the connections are different for 24V than they are for 12V.
Since my heated bed came from my Tevo Tarantula, it is wired for 12V. There are 6 wires that go to the bed. 2 toward the center of the bed, 2 yellow in the center of the connector, and two black toward the right side of the bed.
Red is +12, black is ground and yellow is the temperature sensor. There is a pad glued to the back, which then has insulation and then a foil plate, so if there is a wiring diagram, it cannot be seen.
I think I should hold up until I get a new heated bed.
I'm looking at this one (I'd appreciate an ok) https://spool3d.ca/300mm-x-300mm-heat-bed/ as it looks like I should be able to solder it up fairly easily.
Any chance of converting the old one?
Thanks

@timvukman, it may be possible to convert the old bed heater. If you post some pictures of it then I may be able to advise you. Someone else who has the same printer may already know the answer.

Hi:
In the interest of safety I have decided to replace the heated bed without trying to convert it for 24V. I scraped the insulation off the back and there is no key table printed on it to identify which connections to use for 12V or 24V. It is quite possible / likely that it is not intended for use with 24V.
Thanks
Tim
