@fcwilt Swapped that all to mesh.g and called G29 instead. Redid, MBLA, Z Trigger height, and ran a 100 point to start. Definitely yield improved results and is functioning correctly. Just some fine-tuning and I think I will eventually implement something like a 400-point height map once more things on the machine are finalized. Thanks for the help as always! Your explanations are always a nice balance of basic enough to fully understand but not patronizingly so

@Mr-Yod @jumpedwithbothfeet

Originally I tried the actual outX pins on OUT4-6 to no avail so I tried the tach pins, but I'll switch back. The jumper for the OUT4-6 is on the 12V connection.

Just tried powering the relay board with an external 5V and used the out pins (instead of tach) and still didn't have any luck. Seems like it's a board issue then, I'll have to find a new one or use the remaining IO pins I was hoping to save.

Thanks for the help, hope everyone has had an enjoyable holiday.

Over Extrusion ended up being the problem on this one. After dropping the DWC EM control down to 75% yielded proper layer width, height, and adhesion. A few questions on what to do with this information.

Does anything from the DWC extrusion factor control actually stick or is just for watching live and then going into my configuration file and adjusting?

Is there a flow test or calibration I could run to double-check/calibrate this properly? I thought my E-step calibration would mostly account for this error but that doesn't seem to be true.

@jrcl said in Servo Configuration Check:

@fcwilt I don't unfortunately. I'm no electrical engineer, but could I use some sort of amplification module on the signal? Not sure if PWM signals work like that/or can be amplified like that.

Managed to find the control signal specs. What are the PWM signals on the Duex able to supply?

@phaedrux The M997 S1 command fixed it for me. Amazing! Okay back to your walkthrough

@the-chairman I'm not an expert but this would be used if you used the VIN terminals on the board to power your bed, which you would know. Seeing as you're using a 120V bed with an SSR you probably aren't using those.

Just an aside. Got in my MG995S servo and swapped it out and was rewarded with immediate success. Still interested in hearing your findings on the higher torque servo signal @fcwilt

@phaedrux You guys are awesome! I have 3.3 and updated paneldue firmware on the machine successfully now. Thank you!

@the-chairman That is for Marlin firmware and you are using reprap. To my knowledge the U argument is not supported by Reprap 3.3. While both based on G-Code they have some subtle differences so try and use this g-code dictionary as much as you can!

There are a few choices when manually tuning but to my understanding using R, C, and D are the easiest as you can calculate them with a stopwatch and Duet Web Control (DWC).

@phaedrux Awesome! This is the type of stuff I was looking for, much appreciated.

It ended up being the Z Step after all. Ended up having to double it to 800 steps/mm. For anyone who stumbles on this, I'm using Prusa MINI + Z-Axis lead screws.

@o_lampe Thanks for the insight! Just some additional clarification

So other than the logic being wrong, I need to either jumper 5V to the fan ports and use those instead, or add in a level shifter board so I can drop the 12/24V heater signal down?

However, using the M42 command to set the pins to HIGH and LOW is the correct way to do it. I just need to make sure the logic is proper.

@dc42 Aha! That fixed the problem, Z is homing as expected now. Thank you!

@phaedrux The thermistor had in fact gotten further away from my element than intended. Thanks for the reminder, things are working as expected again!

@Phaedrux Does it only need the part cooling fan noted here because the other fan has been associated with the heatsink through the heater definitions?

@infiniteloop Pulling it through GND and putting the positive terminal on the 5V pin did fix it though! Thank you!

@droftarts this was what I needed! I had been using the table above that, that says PCB Pinout, but I'm now realizing it's for the BL Touch's pins not the boards. Thanks!
