yeah, that is your printer.cfg, not mainsail. It is looking for thermistor, and heater
@orob did you install the mainsail macros when you did you install? If so those macros are probably looking for the extruder. you can get to that mainsail file with winSCP and then comment out the macros in there.
Thanks for the replies and interest.
every line with “extruder” in it is commented in mainsail.cfg. There are no references to it in printer.cfg and I will post the cfg file later this evening.
the printer.cfg file:
# This file contains common pin mappings for MKS Robin Nano V3 boards. To use
# this config, the firmware should be compiled for the stm32f407. When running
# "make menuconfig", select the 48KiB bootloader, and enable "USB for
# communication". The "make flash" command does not work on the MKS Robin.
# Instead, after running "make", copy the generated "out/klipper.bin" file to a
# file named "Robin_nano_v3.bin" on an SD card and then restart the MKS Robin
# with that SD card. See docs/Config_Reference.md for a description of

Yup there are some things that might not directly state extruder but invoke something that calls for extruder. Like I said, best to start with a clean printer.cfg and start building piece by piece. Start with just setting your serial for your mcu(s), then start adding X, Y, and Z axis/motors, and go from there!

ok. the offender was the definition of the controller_fan in the fan section. I want to have control of 3 fans:
- raspberry pi cooling
- driver cooling
- case cooling
I had intended the driver coolling to be the one defined as the controller, so if the cnc was moving, the fan would power on. Klipper thinks if there is a fan, it must be part of the extruder.
here it is in “operational” mode, though it isn’t quite operational.
I have fans that are based on the controller temps without issue, if you’d like I’ll run out and turn on my machine and check the cfg for that. (I think that’s what you’re saying you’re having issues with)
Having the fans declared as they were was the problem. There is a way to enable an aux fan.
I have one on the 3dp. I’ll get that set up.
This might help you for 2 of them…
I have these set up on my V5 and they work well. The controller_fan kicks on any time the stepper is active. and the temperature_fan ramps up and down depending on the temp of the cb1/pi

the term “controller_fan” triggers the extruder error.
So, I now have this that works to at least allow the controller to communicate:

Full physical functionality has not yet been tested. The second and third fans are not yet connected, but this is progress and I appreciate the help!
edit:
changing the first fan from “controller_fan” to “fan_generic” as per klipper docs passes the boot check as well.
Yeah I see it now… It defaults to extruder I wonder if you can put something like heater: none in there? I doubt that will work but there should be some kind of way around it lol.
good thought. no dice:
I think with the generic heater, I can multipin the enable on the tmc and use that to trigger the fan, so if the steppers are on, the fan is on.

Not worried about the fan at the moment. I figured out the one motor issue and the idler was just on too far and rubbing the motor housing or bearing race, so back to the klipper advances.
Vern, my primo’s alias is booted up and I need to verify motor placement/ assignments and directions. First thing klipper requires is a homing step. I don’t recall if there was or was not a way to bypass that so position on startup is home. It would be easiest right now to bypass so I don’t wreck the new printed parts with motors that want to go in opposite directions. Anyone know how to disable the home requirement?
Side question not directly related, but having to do with klipper… Anyone know how to get the timelapse to render even when the print is cancelled?
You can run SET_KINEMATIC_POSITION [X=<value>] [Y=<value>] [Z=<value>] and it will set it as that and allow you to jog around. G-Codes - Klipper documentation
This is something I haven’t messed with at all yet but hope to soon. My camera situation sucks at the moment but I have been lead to a much better option that I hope to check out soon. Keep us posted on anything you find please!
Thanks for this.
I’ll try it later today.
Wrt cameras, I have had pretty good luck with basic USB webcams on the pi using crowsnest. Not great luck with the pi cams so far though.
I think there is room in the macros to force a render on cancel… But don’t know the syntax to do so. I’ll search that up when I have a minute.

Thanks!!
I tried it like 10 times with different macro names and indenting… lots of things and kept getting “invalid code section”
[gocde_macro SET_HOME_XYZ]
gcode:
SET_KINEMATIC_POSITION [X=0] [Y=0] [Z=0]
After remembering how to spell, this works:
[gcode_macro FAKE_HOME]
gcode:
SET_KINEMATIC_POSITION X=0 Y=0 Z=0
I’ll blame this on my reading glasses. c’s look like o’s from a distance sometimes…

this is what klipper control of the primo looks like from my laptop. Had to reverse the left motor for the Y movement and the z motor connections need to be verified, but x worked out of the box.

Z motor connections don’t “look” bad. But the motor only goes down: loudly and in a jerky fashion, so the z motor wiring is not ok. Last time this happened, there was a broken wire.
Edit: red and green wires were swapped. Not sure how that changed. But + goes down and - goes up. Easy enough to switch if wrong.
Next issue is the z end stop with the v1e clamp and pad. It is always triggered.
Using PB8 on skr pro which is labeled as z input. Tried with and without ^. No go. Maybe I’ll try E3 input channel.
UPDATE: one of the two wires ohms out to the touch plate clip. the plate itself does not ohm out, so there is a break somewhere between the plate and its connection to the first extension in the cable chain or the one in the x tube or the one in the side tube or the ethernet plug that goes into the controller box. Three of those are in very hard to reach places…
Update Ii: the break was at the rj45 connector inside the control box. Ohmed out the cable and got the spot to a 1 inch region. Soldered and now all end stops work. System homes x and y. I’ve never had it home z, but the end stop indicators trigger when refreshed. Need to set the z homing offset then try it.
