When I run sudo apt update, hit 3 returns: unstable InRelease Is there a way to download a previous release that is stable?by benkitesurfs - Firmware - experimental, borrowed, and future
I've been following @gloomyandy guide to setting up an SBC for the SKR1.4: I got the raspberry pi all set up, but when I run the script (the one written by PCR), I get errors while processing certain packages: dpkg: error processing package duetcontrolserver (--configure): installed duetcontrolserver package post-installation script subprocess returned error exit status 1 dpkg: dependency prby benkitesurfs - Firmware - experimental, borrowed, and future
I am running in spread cycle as well. My printer is in the garage, so I couldn't give 2 sh!ts about the noise Still way quieter than my DRV8825s that I was runningby benkitesurfs - General
Thanks for your reply! I had previously turned my acceleration and speed down, but that alone didn't solve the problem. I kept cranking up the current last night, and I settled on 1.45 amps which resulted in a max temp during my test of 52˚ C I went on to do an 8 hour print with no problems at all! I did measure the motor temp a few hours into the print, and it was 61˚, but it sounds like thatby benkitesurfs - General
I am running RRF 3.2_1 on an SKR 1.4 Turbo My stepper drivers are TMC2208 - set up in spreadcycle mode I am consistently getting layer shifts in the Y direction. I have reduced my acceleration in the Y direction, and I can continue to do so, but I want to make sure that I am getting maximum torque out of my motor first. The motor is a plain NEMA 17, I don't know anything else about it as it cby benkitesurfs - General
@dc42 I'll check that out! I need to finish configuring RRF - I just did the bare minimum and loaded it up to test it. @DragonFire Thanks for sticking with me on this, and giving me a lot of great ideasby benkitesurfs - General
I have a solution! This is 100% a Marlin problem. I decided to try RepRap firmware this morning, and the results are astounding. One PID autotune (about 5 minutes), and the hotend is hold temp with less than 0.5˚ deviations! Check out this flat line!!!by benkitesurfs - General
The BANG_MAX seemed to make it better, but its far from perfect. I think I'll try to adjust K1 again? PID_FUNCTIONAL_RANGE didn't seem to have any significant effect. I did have one PID autotune that failed - oddly enough, the temperature curve during the failed autotune is the flattest line I've seen in a while...by benkitesurfs - General
Good suggestions, I'll give it a try. I have a layer cooling fan, and it does seem to cause the temp to drop when it comes on. But I can't keep a steady temp even when the fan is not on, so I think that's a separate issue. When I run the fan I always run it at 25%, since its a radial fan, and its pretty powerful.by benkitesurfs - General
I'm completely out of ideas. New heater cartridge. New thermistor. Switched to the other (E1) mosfet on the board. Installed a 1000uF cap (according to Michael at Teaching Tech: ) Looked at voltage from the PSU with a multi-meter (not a scope, so variation could be occurring faster than I can read on my meter) during heating. about 20 PID autotune attempts, with different combinations of vaby benkitesurfs - General
I am using a silicone sock. I took the wire loom apart and replaced the extension cable to the thermistor (its the E3d one with the plugs on the thermistor), but that hasn't made a difference. My bed heater goes through an external Mosfet, so its actually low load on the control board itself. My new heater cartridge will arrive tomorrow, so hopefully that will solve itby benkitesurfs - General
This was my latest attemptby benkitesurfs - General
Thanks for your response! I did figure out how to reassign the pins - they were in the SKR commons file, I was looking in the lpc1768. After switching things over to the E1 mosfet, not much has changed. I can get through a PID autotune now, but the after changing the numbers (and verifying that they're saved), my temperatures are not stable. I get continuous oscillation of about +-5 degrees,by benkitesurfs - General
Ok will do. I am trying to do the experiment you originally suggested (using the E1 mosfet in order to see if the e0 mosfet is the problem). I have never used dual extruders before, but I went into my firmware and set: #define EXTRUDERS 2 #define TEMP_SENSOR_1 5 // same thermistor number as TEMP_SENSOR_0 I changed my octoprint settings to dual extruder, moved my thermistor over, as well as myby benkitesurfs - General
Thanks for replying! I checked the resistance in the heater cartridge, and it seemed reasonable at 5.2 ohms (its a 12v 30w E3D cartridge - supposed to be 4.8 ohms) I disassembled the system again, and made sure everything was tight. I ran PID again, this time starting with 0 values for all 3 parameters, running a short autotune at 180˚ (4 cycles), inputing those values, then repeating the autoby benkitesurfs - General
I have autotuned my hotend and bed many times before - I usually use the temps that I run for PETG, since that's the filament that I used the most, and I do 8 passes. For the hotend that is M303 E0 S250 C8 Last night I changed out my heatbreak and nozzle due to continued clogging that was not resolved after multiple cold pulls. After, I decided to run PID autotune on the hotend. When I do, thby benkitesurfs - General
Thanks for your reply. As I was reading it, I realize what I have done. I was being dumb - I guess I just had to walk away from it: I had initially only put power to the center 2 pins, to power the logic, so that I could load the firmware. I totally forgot that this board has motor power on separate pins. I just put power to the motor pins, and everything appears to be working now.by benkitesurfs - Controllers
Hello, I just purchased a RAMBo from Ultimachine. I downloaded a fresh copy of Marlin, and began configuring it (motherboard, enable the smart controller, etc). When I uploaded it to the board, everything responded as expected, the LCD works now. But I have no response from the steppers. I have measured the voltage across both coils, on multiple axes, and there is no voltage present. Is theby benkitesurfs - Controllers
