Heater Cartridge Error

LZTInc

Hello everyone

I am attempting to resolve an issue. I am a new employee working for a company that is using a Modix 3D Big 60 V3 printer with a Duet 2 WIFI board. We recently had to replace the heater cartridges (the ceramic part that heats up the extruder) but we keep running into the following error: "temperature rising much more slowly than the expected 1.6 C/sec". We have followed customer support on how to troubleshoot and have not been able to pinpoint the issue. We have replaced the heater cartridges multiple times and checked the electrical connections. I began to check the Duet documentation and says that the heaters have to be calibrated via PID and the error we receive is due to the heaters not being calibrated. There are macros on the Duet that runs the PID auto tuning but want to confirm that this is indeed the source of the error and the heater can be auto PID tuned using this board and firmware vr. If there are any other suggestions, please let me know

Tech Specs

Firmware: RepRap Firmware for Duet 2 WIFI 2.05.1

@lztinc The firmware of your Modix isn't up to date. If you want to stay with RRF 2.05.1, you better follow this (now outdated) document, see: Firmware 1.18 to 3.1.1

@tecno Thank you for the response. As a quick follow up, there is a macro that PID tunes the heater on the board. Can I run the macro for my board rather than run M303?

Thanks

@lztinc what's the contents of the macro file?

@rushmere3d
Macro "PID E0 - Run"

M300 S666 P666 ;
M291 S3 R"Attention!" P"During auto tuning there is minimal protection against heating faults. Therefore you should not leave the printer unattended"
M570 H1 P120 T50 ; Extend the heater H1 fault timeout to 120 seconds for testing
M106 P0 S255
M106 P1 S255
G4 S1
M303 H1 P1 S240

@lztinc Yeah that should be fine, it's going to do a couple of things like show a message and then set the printer up for a PID.

Currently doing a test print but seems to be working. Thank you all so much for the help

I believe Modix has support for RRF3 now and should be able to provide you with more details and config changes required.
