QuoteAno Did you check if 230 degrees are "real"? Or is it just the electronics showing that value. Try to check with another thermometer. My idler sits on a slight angle, too. Perhaps you should try to find a solution without the nozzle installed. Just check the extruder itself. Is your hobbed bolt working correctly? So I had bought an IR thermometer at Harbor Freight and the temperatures areby LittleMike - Prusa i3 and variants
QuoteAno Hey LittleMike, never give up! ^^ Did you check the temperature? Perhaps the thermistor isn't working properly. A too low temperature could be the problem. If that's not the case, try to tighten up the nozzle while being heated to 230°C. Perhaps there is a little gap that's blocking the filament to flow. Other than that: Try not to turn the tensioners in too much, otherwise it could alby LittleMike - Prusa i3 and variants
Hey all, I'm ready to buy a new hot end and extruder out of frustration for not getting this printer to work. It's been almost a year since I first built it and real life got in the way, but this weekend, I've been working on it and pulling my hair out.

Quotepierrehavelaar The idea is that you can move it up and down by hand so you can feel how smooth it is moving. Right, but it would only show me how smooth it is moving up and down the smooth rods, which doesn't help the issue of the left nut falling out of the trap every time the x-carriage moves down. I removed both threaded rods and put them back together because they got misaligned (the caby LittleMike - Prusa i3 and variants
Quotepierrehavelaar The weight of the x-axis will press down onto the nut with the x-idler. I think you should remove the threaded rod or just move the nuts all the way down so you can check if the X-carriage can move freely and smoothly up and down the Z-axis rods. Perhaps the rods are misaligned causing extra friction in the linear bearings. If that is fixed you could add a little silicone baseby LittleMike - Prusa i3 and variants
Quotepierrehavelaar You are probably hitting your bed or some other obstruction that is lifting your X-axis of the nut. Otherwise it should keep in place by gravity. Make sure you place your Z-endstop correctly and the have configured it correctly in firmware. But I'm nowhere near the bed when the nut starts to drop.

No suggestions as to how to fix the slipping nut issue? Is there a type of glue that will bond metal to ABS and not melt the ABS? (like to try and glue the nut to the inside of the nut trap on the X-idler?)by LittleMike - Prusa i3 and variants
Okay, so I think I got the endstop issue figured out. I was using Marlin 1.04 and I think I had something misconfigured. I switched to Marlin 1.0 and no more issue with them showing as triggered when I send an M119. Mechanical issue - the nut that is kind of pressure fit into the x-idler that the threaded rod goes through keeps coming out. When that happens, that side no longer moves up or downby LittleMike - Prusa i3 and variants

Hey all, Haven't made any progress at all. In fact, I feel like I've gone backwards. First I relocated the motor that's in the front of the y-carriage in the build instructions to the back right (when looking from the front). That moved just fine, but then I had hard time getting everything 245mm from frame to front again.
