T0 belt slipping/mechanical problem? (IDEX)
For the last two weeks, I’ve been trying to fix resonance issues on my T0 printhead. At first, I thought the problem was caused by unequal belt tension. However, after printing the GATS test and re-tensioning the belts, the resonance was still present. The graphs shown were taken with a 3.2 kg weight (I also tested with 2 kg, with similar results).
As a next step, I disassembled the motors on the left side that drive the T0 axis, and reassembled them while carefully checking each pulley to ensure smooth rotation (including the gantry pulleys). After reassembly and belt re-tensioning, I noticed that the belts for T0 were moving up and down significantly (see video).
For now, I skipped the input shaper results and tried printing directly, but T0 experienced severe layer shifts, most likely due to belt slipping....
Beacon angle off…
So I have a major issue getting my V-core 4 to put down any first layer I would call consistent or even mediocre. For months, I have been troubleshooting everything I have read that could cause issues with the first layer. By a fluke, when I was taking measurements, I noticed the Beacon PCB was anything but straight.
It slopes due to the printed part is badly printed, and the inserts are not put in straight.
The distance from the nozzle to the bed in the photo is 0.5mm.
The distance from the back of the beacon PCB to the plate is 3.2-3.4mm....
Firmware installation problem
I'm hoping for some help with troubleshooting my RatRig v300.
I have a Pi 4 controlling a BTT Octopus v1.1, running RatOS with klipper.
After good operation for about 18 months I recently had issues where I felt the MCB was failing (motors seemed to loose power) so I got a replacement and decided to update everything. The Pi updated well, and all Ratos modules updated but I can't get the MCB to flash automatically. I've tried SD flash also, but I keep getting back to the 'board detected but unresponsive' message.
I tried the original board again and same thing. Great care taken will all jumpers etc, and the fact that the old board is behaving similar to the new one suggests I'm doing something dumb when I try flashing, rather than it being a hardware issue. I reformatted the SD card fully, got the firmware binary from Mainsail (firmwar-btt-octopus-11.bin) and it turns into FIRMWARE.CUR after my attempts.
Software, firmware is not my strong suit so any suggestions what could be going on would be much appreciated....
Extruder Temp Error in the Middle of a print
Im getting the following error mid print. Im guessing my Rapido is going out, if anyone knows anything would appreciate it
MCU 'mcu' shutdown: ADC out of range Sensor 'extruder' temperature 327.031 not in range 0.000:300.000 This generally occurs when a heater temperature exceeds its configured min_temp or max_temp. Once the underlying issue is corrected, use the "FIRMWARE_RESTART" command to reset the firmware, reload the config, and restart the host software. Printer is shutdown...
