I’ve got a little problem, I was printing and the filament got stuck while I wasn’t watching. Is there anyway I can send a line of g-code to rewind 28 layers, or to jump to line 267123 in my code? I am using Repetier Host 1.6.0 with a Marlin RepRap printer (ThreeUp from Q3Dprinters)
Found this to be helpful (Although I’ve never done it myself)
@Kalvin_D Thanks, that’s a great help.
I’ve followed all those instructions, I’m just worried about the printer starting with an E value of 7025.27070. Is there a way to set the E value to 7025.24265 (the position at the end of the previous step) before it runs the rest of the code? Or to set that as the home E value before it starts?
Also, somewhat unrelated, it warps when I start this print, because of the curve at the bottom of the object. How do I prevent that?
@Kalvin_D that’s my instructable! Glad to hear that someone found it helpful 
@Aaron_Roth you can set the E value by using the command E92 E7025.24265 bit the difference is so small that in your case it probably won’t matter.
@Markus_Granberg it’s the difference between 0 and 7025 that I’m worried about. I stopped the print and copied the last part of the code and am going to try starting the last part as a new code. Is it E92 or G92?
Sorry it’s M92. If you follow my instructable your supposed to zero your extruder. But if you want to start at 7025 you can try that. Let us know if it works
@Markus_Granberg I just looked it up on the RepRap wiki, It says G92. I’ll try the 7025.24265 in my code. Also, my extruder is currently sitting at Z=39.50. How do I tell Repetier host that? Is it something like G92 Z39.5? Also do I need to set absolute positioning or extruder in absolute mode at the beginning of the code? Also, is there a way to put a manual pause in your code?
Edit: added them in anyways. Hit print, I hope it works out.
Edit 2: it finished great.
awesome!
