Complete sample config file for using Duex2 with 2 Z motors
-
Hi dc42
Thanks for the update. I have not added jumpers to ZA, My Z endstop is still on the duetwifi and I appreciate the clarification on M584 mapping / general mapping.
I did use the wiki page for Makerbot endstop information when I installed them some time ago. That is how I got them working. I have no issues there.
Today I am looking at why I have no axis motors working. I upgraded carefully to 24V and added the Duex2 at the same time. Never a good idea to do two things at the same time. I am trying to reverse the Duex2 install to try to get back to a working duetwifi board on it's own.
I need to go back to the original step by step setup instructions to see what went wrong.
One of these days I will learn to save config files out to the desktop so I have a path back to where I was
Another learning opportunity
thanks

Make sure that your M584 command is earlier in config.g than your M906 command.

Ok:
I have rewired and reset my DuetWifi board without the Duex2, but still under the 24V power supply.
My axis motors do not operate via the Web interface.
All new G Code files were created and put on the SD card with the configuration utility.
For some reason, Wifi is dropping and then not connecting.
If I go into the Machine Control Panel of Simplify 3D, I can move each axis and home each axis with the Jog Controls via USB.

M501I'm still looking into possible reasons.

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.

@dc42
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

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
Tim -
@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
