@coseng The bed plate acts as a heat sink for the heater. In the exposed areas the heater may get much hotter than the areas covered by the plate. I had the adhesive on a heater let go a couple years ago creating air bubbles between the heater and the plate. In the areas with the bubbles the heater burned.

@mrehorstdmd Ugh, I didn't think of that, thanks for pointing it out. Oh, well, I can put some thinner sheet in those areas to get the heat out.

Doing some last wiring and have a question on the paneldue 7i. I would like to use that SD card, so would use the 4 wire connector to IO_0 and the modified 10 pin ribbon cable to the temp daughterboard connector. Is the card detect modification to the 7i pcb necessary or is it just a convienence?

coseng

@coseng Actually, I have a paneldue 7i 2.01, so the card detect signal is present, so the last question is no longer relevant.

coseng

OK, I was able to get it all connected to the PC, uploaded RRF3.4 and was able to set the network parameters and get to the Duet Web Control page on a browser.

I did have some issues with the paneldue7i, so any advise you can offer is appreciated, @dc42 .

The paneldue 7i was connected and seemed to respond very slowly to any touch commands. I had the 4 wire and the modified 10 pin ribbon connector attached. I went to upgrade the paneldue 7i firmware according to https://docs.duet3d.com/User_manual/RepRapFirmware/Updating_PanelDue. It seemed to complete successfully, there were no errors in the console and the last message was:

Progress: 100%
Writing PanelDue flash options
Restarting PanelDue

After the update the paneldue was completely a white screen. I tried pressing reset with no change. I powered it all down then back up and was able to reconnect to the Duet web page, but still nothing from the paneldue 7i but a white screen. Can you brick a paneldue?

Before trying the PC/usb approach I wanted to see if there was something I was doing wrong with the Duet approach.

Use the PC/USB approach. Chances are you had an older version of PanelDue firmware on there that wasn't ready for updating via duet.

coseng

@phaedrux Thanks, that worked!

Now a couple of more questions. Below is my first config.g file. I have not run it yet as I have to run a new AC power socket to plug into, so all of my playing around so far has been only with the USB and network cable attached.

First question from the RRF config tool on i/o mapping tab: PWM Control Channel (BLTouch only) should be set to what value? The BL Touch channels selected on the prvious page are not selectable on this drop down. I left it not assigned, but on the next page the BLTouch entry was greyed out. the BLTouch is on a 1LC toolboard. and all 5 wires are connected as shown in the wiki, so am not sure what this is referring to or how it would be wired.

I have a Z limit switch at about z=0 (or can be positioned wherever is convienent) and a BL Touch. What is the preferred way to home Z? Is the limit switch even needed?

I am running the 5V line that supplies the BoB with power to generate proper level clearpath signals from IO_3_out. What would be the command to turn this output on to power the steppers?

Also, not sure if it should work with no 24V supplied, but the Paneldue 7i upgraded fine and displayed a proper screen when plugged into a USB cable, but when plugged into the 6HC (powered by usb) with a 4 wire connector and 10/7 pin ribbon cable (both are correct) it only gives me a white screen and does not respond to touches. Also, a reset does not seem to do anything.

@Phaedrux One more question, I saw the paneldue initialization line at the top of config.g, but nothing metioning the SD card access through the temperature daughterboard connector: M950 D1 C"spi.cs0+spi.cs2" . Does this need to be added manually or does the M575 take are of it?

Phaedrux

@coseng said in New heated enclosure printer:

M558 P9 C"121.io0.in+121.io0.out"

It's not showing the PWM control channel in the drop down because you somehow have both of them selected for the probe input.

You can manually edit the config.g to correct it like this.

@phaedrux OK, got that taken care of. Was confused that the Modulation Pin needs to be not defined.

I installed AC power and powered it up. Nothing smoked, so that was a good step. I do of course have a couple of problems:

-1LC toolboard is not in CAN sync (fast blinking LED) tried reset to factory but no go. I'm pretty sure the wiring is correct. The extruder fan is on. Vin and 5V leds are lit. tried sending a query over the web interface with this response:

Error: M115: Response timeout: CAN addr 121, req type 6024, RID=14

-chamber temp sensor is reading at 2000C, but a multimeter reads 226kohm across the plug, which is two pt1000 sensors in series.

-when I go to home an axis I get a 'failed to enable endstops error'

That's almost certainly caused by a wiring error. Perhaps CANL and CANH are swapped betweeen the main board and the tool board. Can you post a photo of the CAN wiring?

-chamber temp sensor is reading at 2000C, but a multimeter reads 226kohm across the plug, which is two pt1000 sensors in series.

Did you mean two 100K thermistors in series?

-when I go to home an axis I get a 'failed to enable endstops error'

That's because the endstop is configured on the tool board and the main board failed to communicate with it.

coseng

@dc42 Here's a pic of both ends of the CAN line from the TDB to the 1LC. I used the provided RJ11 cable for the 6HC to the TDB.

The about 2m long purple cable is a CAN rated cable from McMaster, 8097T21. Connectors are 3M IDC style, 37304-3101-0P0FL-8P from Misumi. I checked continuity from end to end.

The temp chamber sensors are 2 PT1000 in series. They have the blue mesh wires and check out in a multimeter individually and wired together.

coseng

@dc42 @Phaedrux Sorry to be so needy on a holiday weekend, but any ideas? I've tried fiddling around with no luck.

dc42

@coseng I suggest you use a multimeter to check for continuity between CANH on the 6HC and CANH on the tool board. Similarly for CANL.

Another test you can do is to measure the resistance between the 2 jumpers on an unused port on the distribution board. It should be 60 ohms if the connections are sound. But this doesn't check for CANL and CANH being swapped between the main board and the tool board.

Both tests with power off, of course.

coseng

@dc42 Thanks for responding on a holiday weekend. Traced it back and found that I somehow damaged the provided RJ11 cable. Swapped it out and now the CAN bus is synchronized and the nozzle temp is correct.

Chamber temp still reads 2000C and is two PT1000 sensors in series.

Now on to some motion problems. If I issue a M564 H0 and go to the 'move' page, Z moves without a problem but X and Y do not respond. If I then go back to the main page and try an individual axis home, z moves a little if any axis is pressed and a 'G0/G1: insufficient axes homed' error.

I'm pretty sure all the roach wires on the stepper signals are correct, and wired the BoB according to this image:

Only X and Y are connected.

coseng

OK, looking in the files and seeing that all the home moves move the Z axis first means that Z moving first when doing a x or y homing is not a problem. So now to figure out why the clearpath motors are not moving and the chamer temp is not reading correctly.

coseng

@coseng They are not moving because I have not turned the 5V output to it on! Is there a command to do this through the web control?

coseng

@dc42 To turn IO_3_out on to 5V, do I need to define it as a fan then turn the fan on at 100%?

coseng

@dc42 I'm a stumped and at an impasse if you can spare a little time to help. Everything works but the chamber temp sensors (2 PT1000 in series) still reads 2000C and I can't get the X or Y motor (Driver 1/2) to move through my roach wired BOB arrangement. Z moves fine through Driver 0. I've triple checked the roach wiring and it matches this 'schematic':

I have the 5VDC to the ClearPath's (+) inputs wired externally to the connector thought the 5VDC pin on the 3 pin connector. This allowed me to test the polarity as you indicated in your previous post: 'If you are using single ended 5V drive, then connect ENA+ of your servo to +5V, and ENA- to either Enable+ or Enable- on the EBOB, whichever gives the correct polarity.' Enable- ended up working.

The motors are both enabled (a status LED on the motor body is in the 'enabled and waiting for a move command' state). But I can't get motion with the Clearpath's (-) step and direction lines connected to either BOB connector's polarity. See image.

I'm not sure if I should try swapping the clearpath lines around so +5V goes to brn/yel/ora instead of whi/blk/blu.

Any suggestions are appreciated. Here is the config.g file:

@coseng you need to use M569 commands with T parameters to lengthen the step pulse timing for external drivers. See https://docs.duet3d.com/en/User_manual/Connecting_hardware/Motors_connecting_external#configuring-the-step-timing.
