Completed my Axis build, other than all the "manufacturing & shipping oops" I had to deal with: LCD cable plug notches backwards, hot end cables too short, eccentric instead of fixed guide for Z-axis sent, power plug nut pretty much stripped the plastic power plug right away... everything but one thing seems to be working well. Er, also blue knob and/or screen seems to be locked up while printing my first print.
Main concern I have is that the Heated Bed can't seem to accept a setting above 45-degrees Celsius. I thought it was just Pronterface/printrun. The terminal session would say Setting Bed Temp to 60c ... but the status line on the left under the XYZ controls would say 45.00 degrees. It would hold steady at 45.00/45.00 as well. I can't see that I've done anything wrong, line 417 in Arduino IDE is "#define TEMP_SENSOR_BED 1" was already there and I didn't change it. Looking for "BED" in the IDE, I see this on line 461: "#define BED_MAXTEMP 55" - I'm not sure if that is degrees, or a percentage or a number out of 255 or what... but it isn't 45, so I don't think that is it either. Any ideas?
Benchy first print from SD-Card also said 45-degrees Celsius even. I can't get back to the info screen either. Benhcy has been printing for about 25-minutes so far (looking good), but turning the blue knob or pressing it does nothing. Just sitting on the "Info Screen up arrows", then Pause Print, then Stop Print, then Tune... but pressing or turning the blue knob does nothing. I disconnected my laptop before starting the print.
Benchy finished up, definite "waviness" on the cabin wall, assuming I should try to make things "tighter" but not sure how to do that and actually have them moveable. After the print was complete the knob control and screen became unlocked again.
Glad the build mostly worked. My first 3D printer build. We got a Prusa i3 MK3S as well a couple weeks ago, but that was pre-assembled, that's what printed the fan shroud.
Looks like the Kickstarted email pointing to the Tips & Tricks FAQ has a new Configfuration.h file... looking through that, line 461 changes:
#define BED_MAXTEMP 70
So, there we go. Mine was set to 55... assuming with that number that it is -10 for whatever is setable so, 45 before and with 70 it would be 60. Also changed the printhead from 250 to 270, again, so I bet I can set 260 now instead of 240... not that I have a bed hot enough to actually need to set that.
My Mean Well LRS-350-24 came today. Need to print a cover for the terminals (and the switch). I have metal couplers, reading the FAQ though, sounds like that might not make too much of a difference since I don't think I have Z wobble, I just have Y wobble or the bed/X wobble. I've greased on the rails that slide against the guides and it helped a little, but not completely. Will put the metal coupler on and again will re-adjust all my guides.
FAQ also addresses the TMC Error... but I've done all that, so they don't say how to tell WHICH TMC2022 driver is having an issue. I'll look at the output again in Prontoface and see if I can figure it out... maybe go ahead and finish the Dual Extruder... perhaps everyone who has had issues are using the older version of Makertech Cura files? Since I'm later in building, I am using the later ones (just checked) but they mention retraction length changes in there with the 2.0.1 version so maybe folks should investigate that. Okay, only have an hour to work on this, so off to it!
I know that the TMC error is caused by the incorrect config for the stepper drivers. You need to make sure that the places for the drivers, depending on how many you used, are in the correct position.
If you used 2, then you put 2 in the config. If you have 0, then you didnt make changes.
As far as the bed, they are looking into what the power supply can handle.
The control knob/display lockup did NOT happen with the second print was just the basic dice tutorial in Thingaverse. Not sure what happened last night during the Benchy print. Printing a XYC Calibration 20mm Cube now to see how things are "measuring (and lining) up".
When I plugged the power cords in today, I got a "TNC or TMC Communication Failed or Error" message on the screen. Don't know what that was about, happened again on unplug/replug.
Ordered a metal coupler per advice here on the forums for the Z-axis, and ordered a MEAN WELL DC Power Supply LRS-350-24 for Tuesday delivery (guess I'll be building a case); though not sure how the system would know the wattage of the power supply to limit the bed temp to 45 Celsius... must be something I'm missing.
Hmmm. I used 5. XYZ, extruder 1 and extruder 2. Though I don’t have the dual extruded configured yet, so that might be the problem. That said, I don’t remember putting a number anywhere about the drivers, just changing the definition over and the inverting the directions from true to false and vice versa for the one. Did double check the Arduino setup yesterday... hmmm. Maybe I zapped the E2 driver... or forgot to put a jumper on all the UART pins... will double check tomorrow.
Thank you!
Here was my final first print.
That benchy came out nice! I could never get one to print that nicely.
For the TMC issue: Make sure you have the TMC2208 setup in Configuration.h.
#define X_DRIVER_TYPE TMC2208 #define Y_DRIVER_TYPE TMC2208 #define Z_DRIVER_TYPE TMC2208
The above would be if you had the white TMC2208 drivers for X, Y, and Z. If you have the red drivers for E1 and E2 then you would leave the rest of the lines in that section commented out. If you have the TMC2208's in all the positions then set those as well:
#define E0_DRIVER_TYPE TMC2208 #define E1_DRIVER_TYPE TMC2208
You could have the same issue I had, one or more of your TMC drivers could be bad. I had at least one. If you accidentally put the driver in backwards and turn the board on then there are issues too. The drivers don't like that at all.
On the bed, when you start the printer up and the bed is at room temp, does the screen (or Pronterface) show it as room temp? When you send the command to heat it to 60 does it move up gradually to 45? Try swapping the supply that you're using to run the printer with the one for the heated bed. What does the LED look like on the bed power supply when you set the temp? It seems like some people are getting bum supplies.
