Cancel this one, I was on Buster and not Bookworm. I followed this:
https://docs.duet3d.com/en/How_to_guides/SBC_Buster_to_Bookworm

And now it is working fine on 3.5.2.

Thanks,

Hi all,
I am trying to upgrade my 6HC with a raspberry pi from 3.5.0-rc.2 to 3.5.2 by using apt-get commands and I am getting the following:

@Phaedrux just reporting back that it was definitely the issue. Once I drilled the holes out in the case and re-mounted the PanelDue, the issue was fixed. Thanks!

undefined

@Phaedrux thanks for the reply. When I remove the screen from the case, the issue disappears. My theory is, when it’s in the case, the board twists and causes the digitizer to come off the screen. It was definitely the digitizer as I can tell now that it’s out of the case that the digitizer floats on the screen and is only attached at the edges. I ordered it from Printed Solid on 9/13/2022. I will drill out the mounting holes on the case to prevent it from twisting the board.

I just installed a PanelDue on my 6HC and it’s awesome, but it appears to have a wavy film that doesn’t appear to be fully adhered to something below it. I already removed one screen protector before installing it. Is this another screen protector I needed to remove or is it the digitizer, etc.

That was it exactly, thank you!

Hello,
i have a custom built Cartesian 3d printer with 2 independent Z motors running the 6HC with 3.3 firmware. I noticed when I run repeated lead screw leveling commands, the initial probe before adjustments for every command are about the same and the left side appears to be consistently higher than the right side. I'm using a genuine BLTOUCH for leveling.

I have these commands in my config.g:

M584 X0.0 Y0.1 Z0.2:0.3 E0.4:0.5                   ; set drive mapping
M671 X-20:350 Y150:150 S5; leadscrews at left and right of X axis
M208 X0:340 Y0:310     ; set axis limits

For testing purposes, I configured my bed.g file with the following:

G28 ; home
G30 P0 X20 Y150 Z-99999 ; probe near front left leadscrew
G30 P1 X275 Y150 Z-99999 S2 ; probe near rear leadscrew

I kept repeating the G32 command but the bed doesn't appear to be getting any more level:

12/18/2021, 1:55:32 PM	G32
Leadscrew adjustments made: -0.114 -0.118, points used 2, (mean, deviation) before (-0.116, 0.001) after (0.000, 0.000)

12/18/2021, 1:53:18 PM	G32
Leadscrew adjustments made: -0.164 -0.075, points used 2, (mean, deviation) before (-0.124, 0.031) after (-0.000, 0.000)
12/18/2021, 1:33:03 PM	G32
Leadscrew adjustments made: -0.154 -0.053, points used 2, (mean, deviation) before (-0.109, 0.035) after (-0.000, 0.000)

Could this mean I have a hardware issue or is the adjustment not taking place for some reason?

Thanks much,
Ed

@droftarts Thanks, this is exactly what I was looking for.

@o_lampe Thanks, that was a typo, but the question still remains, how do you change the home offset to compensate for the print head being offset?

undefined

Ignore this one please. I can't delete it. I rephrased the posted a better question here:
https://forum.duet3d.com/post/230220

undefined

I have a 6HC and I'm almost done configuring this custom printer. I have a 330x330mm build plate and the print head is not center on the bed when I go to X=115 Y=115. I have a lot of experience with Marlin and I would adjust the HOME OFFSET to fix this issue (M206). I can't find a similar command in RRF. The closest thing I found was a tool offset but I don't believe that is going to achieve what I'm after. Can someone point me in the right direction with this one?

Here is my config.g file

Hello,
I am working on a new custom build with a 6HC board. I did my initial RRF config using the RRF config tool. Everything is working great but the tool offset doesn't appear to be changing the offset. I have a 330x330mm bed. To find the offset, I am putting painters tape all over the bed, used a straight edge from corner to corner and a marker to find the exact center of the bed (where the X crosses), then issuing "G1 X115 Y115" to have the printer go to where it thinks the center is. I have two extruders so the 2nd extruder is set up as P1. X was somewhat good but Y was way off so I set the Y offset to -80 just to see if it works and get it in the general area. When I change the offset in config.g and restart the board, and re-issue the "G1 X115 Y115" command, it goes exactly to where it was before and it appears changing the tool offset is not affecting the location of the print head. I tried changing it to 80 instead of -80 and tried putting the settings in both P0 and P1, but these didn't work. Any ideas?

Here is my config.g file:

Thanks mucc

@dc42 Thanks! I put the glass bed on before the tuning exercise so the temp of the surface of the bed matches what is displayed in the Duet3d WebUI. It is less than a degree off at both 60 degrees Celsius and 110 degrees Celsius, within the error margin of my thermometer. I am very happy with the results .

I figured out the print bed temperature issue in case anyone else runs into this. I put a thermometer probe on the surface of the bed. I performed a PID auto-tune on the print bed and heated the bed to 115 degrees Celsius (using the thermometer to measure the temperature) since I believe 110 degrees is the highest I would set the bed for printing ABS. I turned off the printer and immediately unplugged the thermistor for the bed and hooked it up to an ohm meter. I watched the thermometer and as the temperature fell. When the temperature reached 110.0 degrees Celsius, I looked at the ohm meter and recorded the thermistor resistance at that temperature. I wanted to record another 2 more temperatures so I took another reading at 60 degrees Celsius and a final one when the bed got to room temperature. I plugged those values into the Steinhart-hart equation and got a beta value of 4116.93. I then updated my M308 command to this (the T value is the resistance of the thermistor at 25 degrees Celsius):
M308 S0 P"temp0" Y"thermistor" T95600 B4116.93 C0

After saving the config and rebooting the board, the bed temperature displayed in the Duet3d WebUI is nearly perfect to its actual temperature.

@dc42 Thanks for the reply! The bed is aluminum. I hooked up a multimeter to the thermistor and brought the build plate to 25.0 degrees Celsius (measuring with an accurate infrared thermometer). The resistance was 95,600 ohms at 25.0 degrees Celsius. I changed my T value to 95600. After changing the value I measured the temperature of the bed which was still exactly 25.0 degrees Celsius. At that temperature, the duet web UI showed a temperature of 27.6 degrees Celsius so it looks like it's still off by a few degrees.

I contacted the manufacturer and they couldn't provide more information on the Steinhart–Hart values. They just re-iterated the fact that it's a "Creality CR-10 replacement bed."

@dougal1957 That was exactly the issue. I looked at the top of the lead screw and it has a 4 start. I changed Z steps per mm to 800 and now it is perfect.

@jay_s_uk Thank you! I tried B4092 but it is still off by exactly 20 degrees Celsius after re-tuning. I think I just need to contact the manufacturer of the bed and ask them which thermistor they used.

Hello All,
New Duet customer here. I bought a duet 3 6HC for a custom Cartesian 3d printer I made. I have two issues. The first issue, the X and Y movement are spot on, but the Z movement is way off even though I believe I have the steps per mm set correctly. I have dual 0.9 degree Z motors. My lead screws are 2 mm pitch 8 mm diameter and the lead screw nuts are correct (I double checked, 8 mm diameter, 2 mm pitch). I have 1/16 microstepping enabled for them in reprap. I put the steps per mm at 3200. When I use the duet interface to manually click Z +5, it moves the Z axis probably 50 millimeters.

Here's the drives section of my config:

; Drives

The 2nd issue I have is my heated bed is about 20 degrees Celsius cooler than the thermistor is registering, even after PID tuning. If I set the bed temperature to 60 degrees Celsius, it will only get to about 40 degrees Celsius while registering 60 degrees Celsius in the duet web UI. I am using a creality cr10 heated bed and the documentation says it has a 100k thermistor on it.

Here is my Heaters section:

; Heaters

M143 H1 S280                                    ; set temperature limit for heater 1 to 280C

Any ideas on these two issues? I might have a faulty thermistor.

@phaedrux Thanks! I will check out that plugin. It looks like the firmware now gets installed automatically when you upload the files without asking you to install it as well.
