Bench Testing Mixing Extruder with Pronterface

@Phaedrux - you may be right - this is what is listed on DWC. Should the Web Interface Version be HTML: 3.0? I'm starting to get very confused...

Firmware Name: RepRapFirmware for Duet 2 WiFi/Ethernet
Firmware Version: 3.0 (2020-01-03b3)
Web Interface Version: HTML: 1.11

Try uploading this zip file https://github.com/chrishamm/DuetWebControl/releases/download/2.0.7/DuetWebControl-SD.zip

@Phaedrux - not able to upload file with DWC - followed instructions here:

https://duet3d.dozuki.com/Wiki/Installing_and_Updating_Firmware#Section_Updating_WiFi_firmware_or_DuetWebControl_files

to unzip DuetWebControl-SD.zip onto SD card after deleting old file contents

issue remains - AJAX error when uploading files via DWC

Phaedrux

Just to confirm, you've wiped out the /www folder and replaced it with the contents of the zip file and the DWC version now shows as 2.0.7?

What browser are you using?

ractorIII

@Phaedrux -scratch that - installed and seems to be in sync now.

still trouble defining tool head - same bounce back from DWC on issuing M563 P0 D0:1:2:3:4

How do you have your motors connected? The drive mappings don't match what you're trying to use for tool drives.

@Phaedrux - yeah - I wasn't sure if the drive should match the extruder number or the drive number, so I tried both M563 P0 D0:1:2:3:4 and M563 P0 D3:4:5:6:7 am getting the same 'tool creation: bad drive number. I read the sections on drive mapping and tool defining and everything seems to be in order. Unless I missed something. Dumbfounded at the moment.

deckingman

@ractorIII The drive numbers used when you define a tool refer to the extruder drives in the order that they are created. So if you have physical drives assigned to extruders 3 to 7 in M584 then the extruder drive numbers when you define a tool are 0 to 4. Which looks like that's how you have done it.

@Phaedrux Nothing happens when I attempt to send gcode through the Duet Web Interface - though the log state that I am connected, the log does not indicate that any code was sent. Another issue that I am having with DWC is that if I attempt to upload the zipped reprap config file I get an AJAX error and it disconnects. If I remember right - I was having this issue before and had to disconnect my power supply from the board and run it strictly of usb to get the upload to work - very inconvenient. I guess I'll open my housing and pull the micro SD out to update reprap config files.

To the issue at hand, which is getting a tool designated for bench testing my extruder setup. The following is how print run responds when issued:

SENDING:M563 P0 D0:1:2:3:4
Error: Tool creation: bad drive number
[ERROR] Error: Tool creation: bad drive number

I'm using a duet wifi with x5 expansion - I have a total of 7 extruder steppers and for this tool I am trying to use the 2 that are on the Duet Wifi and the first 3 that are on the x5 expansion.

Perhaps the M584 command to set up the extruder drives failed. If you send M584 without parameters, what does it report?

EDIT: maximum number of extruders supported by RRF3 on Duet 2 is 6. So your command:

M584 X0 Y2 Z1 E3:4:5:6:7:8:9 ; set drive mapping

is failing because you are trying to create 7 extruders. If you really need 7 then I can increase the limit.

ractorIII

thanks @dc42 - I need 5 extruder steppers at the moment - if that is the case I'll remap my motors so my dual Y steppers are not doubled up on one driver. Maybe that will fix my issue - I'll look into your other suggestions later today.

I would be interested in having more extruder steppers available in the future - or even the ability of mapping all of the drivers as extruders - the goal would be precise stationary liquid slurry mixing machine.

ractorIII

@deckingman - thanks for your help. Eliminating the E6 driver mapping resolved the issue. All steppers are tested to be operating as expected.

I would like to use that final stepper on the Duex5 as an extruder eventually but will not need it anytime soon.

Sorry - this was meant to be a message toward @dc42 :

I'll increase the maximum number of extruder drivers to 7 in the next RRF3 build for Duet 2.
