Join Serverarc fitting problem crash mcu
Hi everyone... I noticed that when printing some round objects, with speeds of 500mm/s and high accelerations with arc settings, the klipper crashes... it gives me the error in the photo... I deactivate arc on the slicer and everything works perfectly... I set arc resolution to 0.1… too low?
homing issue
Hello
When I try to home my Ratrig which is a 500mm build. The home z shows 450 and stops at 448. Upon reversing the direction of z motors it goes up and first error shows is no endstop for z and when I redo it after that it crashes on the tool head....
Question regarding changing thermistor sensor pin
Hi Y'all,
I'm pretty sure that I fried the sensor circuit for the hot end thermistor on the BTT octopus V1.1 board. I'm trying to change the T0 pin from PF4 to PF5 to see if that circuit would fix it(Picture below).
I'm very much a novice with klipper and octopus so forgive the basic questions. Is there a simple way to redefine TEMP_0_PIN in ratos or do I have to build a whole new octopus board firmware.bin with the new pin definitions?...
Getting More Consistent First Layer and Z Tilt Issue Related?
I'm having trouble getting a consistent first layer. I've had this problem before, I do the first layer leveling and get the z offset and I get a good first layer with the test print. But then when I go to print something the first layer is always bad and I get bad adhesion making the print fail usually. Sometimes it is so solid I can't get the print off and other times I just tap it and it'll pop right off. I keep lowering z offset as a result, but then the first layer becomes too or squishes too much leading to a non-flat layer. So then I increase the z offset to give it more room. It really is a pain, and then first layer height seems to impact it as well so I've started just using the same first layer height to try to make it more consistent.
One thing I tried is I thought maybe there's a problem with the z-tilt so I checked all the motors and they corresponded correctly to the expected stepper drivers. I tried lowering the tolerance for z-tilt to 0.01mm instead of 0.02mm, but as a result it seems to fail multiple times with the reason that z-tilt is increasing after 4 tries or so. After a few tries it ends up with a tolerance of like 0.004mm and then it starts to print. So I don't know if that's indicative of a problem or what is going on and why it would be increasing.
The pictures are from what I am getting now and what I was getting before, the blue is the more recent one. I tried multiple nozzles, I don't think it is clogged....
Thermistor wonky when N / L are switched
So my heatbed thermistor (orange) showed weird fluctuations, sometimes random, sometimes very regular.
After a lot of troubleshooting, I noticed it went away when the 230V lines of the heater are not connected. Reconnecting them: wonky again.
I checked all cabling (no change) and then had the idea to switch the plug of the printer around (so switching neutral and live), and now its gone as you can see on the second picture.
So its fixed, but any ideas what was causing those fluctuations? Is that maybe an indication of a bad SSR or something? ...
I accidentally cracked a magnet.
Is it okay that it’s cracked like this? Will it work if I just add a drop of superglue to hold it together? Or do I need to just buy a replacement magnet. If I need to buy a replacement could you please provide a link for the magnet?
idk where the linear rail supposed to be…..
Is the linear rail supposed to be touching the XY idler? Pls help asap!!!
V Minion bed heater issues
V Minion been working fine for months and 1000+ hours. Last week I tried to print and I got not heating errors... sure enough my bed isn't heating at all.
Things I've tried:
- reseated heater wires
- confirmed thermistor is working (to the best of my abilities)...
my aluminum extrusion doesn’t match!
I am currently building my frame of the Ratrig v3.1 500mm and the aluminum matches up on one side but not the other. I am sure that I used the right lengths of extrusion. I am on step 18. Any fixes?
