The heated bed is a 300x300 aluminum plate with a 24V silicone heater, and the hotend is a Volcano clone with a 0. Scheduled Pinned Locked Moved Solved. 1. I have included the text from the configuration at the end of this post. 4, I2. M115 output: FIRMWARE_NAME: RepRapFirmware for Duet 3 MB6HC FIRMWARE_VERSION: 3. g) and check that config-override. Assume I'm running whatever the latest beta/stable build is. Also I decided to use the M500 command and use t The main problem is that I’m unable to complete the PID autotuning process. g I would recommend going bac @noblebran said in PID Tuning: They seem to be slightly different but my heat temp still goes above 250 when aiming for 210. g, increase the D parameter in that command until the temperature is stable when the print head is not moving. x uses a low PWM frequency (10Hz) so as to be compatible with all standard types of SSR. After it runs, send M500. 2 heater tuning issues. 000 D3. 3, I0. 8 Computed PID parameters for load change: P1 The first line are the values that goes into config. 6 13:36:26M307 13:36:00Warning: Heater 0 appears to be over I made PID tuning to my Bed Heater adn result is below. 268:0. It has Nema 23 stepper motors driving ball screws on the x (600mm), y and y Duet3D Tags; Powering a printer and PID tuning issues. Here is my setup info: Controller: DUET 6HC; Firmware: RepRapFirmware Configuration Tool v3. 6, along with pre 1. This allows the PID c I made PID tuning to my Bed Heater adn result is below. 18beta1 you no longer need to specify a P parameter when auto tuning, unless your heater is massively over-powered. . Register; Login PID Tuning. 1 after an initial overshoot of I thought pid tuning was fairly quick? Board: Duet 2 WiFi (2WiFi) Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3. 29 E1. The same PID tuning will behave differently depending on whether the temperature is rising or falling. Do you mean type k thermocouple? @noblebran said in PID Tuning: Duet3D Tags; Documentation; Order; Search. @wilriker said in When to repeat PID Autotune?. @jay_s_uk its all e3d volcano, just replaced everything with this build. Reply as topic once you add M501 to the config, run the tuning again. oliof. 9k. Disclosure: I design Duet electronics and work on RepRapFirmware, . Heater 3 fault: temperature rising too slowly: expected 0. 812 K0. 000 D2. Got the same problem after i updated to reprap 3. 9, time constant 771. Warning: heater behaviour was not consistent during tuning Auto tuning heater 1 completed after 3 idle and 25 tuning cycles in 1410 seconds. Also its going to phase 3, with fan off. I'm looking to print in ABS, so as a test I've commanded it up to 110 degrees. Learn how to tune the heater temperature control using PID parameters in RepRapFirmware. I'm having trouble getting the best temperature control by fine-tuning the PID parameters on my heated bed and hotend. 6 B0 ;PID Tuning Bed M143 H0 S120 ; Set temperature limit for heater 0 to 120C M305 P1 T100000 B4725 C7. During tuning, it's a 10° swing both ways while in stage 2. Reply as topic; Log . g was read at start up) rather than the Just switched the bed to PID as supposed to BangBang since i've got it hooked up to a external mosfet and a dedicated 24V 400w PSU (the rest of the machine runs on 12V).
