Just wanted to be clear if you changed the extruder steper. The OP said you changed the stepers and then the problem started. But we tend to think of the X, Y, z stepers and forget the extruder. So i wanted to be clear if it changed. If it didn't change then that should not be the problem.
And you are correct, it changed the X and Y steppers, Z and extruder is the same as always.

Did you change the steper on the extruder?
You think it might be a "simple" under extrude?

Its increadably consistant. Which direction is the head moving when it leaves gaps? (In picture, left to right or right to left, or both). Looks like some walls have the issue in the opposite direction but doesn't have a complete break.
I dont know, I tried to repeat it tod

I'm running cura 3.6.0. Both cura project and gcode attached here.

print head is moving in one smooth movement from outer wall to outer wall, or so it seems when looking at the machine working.

It is indeed Curas default infill, and the same g-code on my other machines does not produce these gaps.
The machine in question is a rather hacked repstrap build, so it can be almost anything there not very well designed/built. Which is why I ask for some suggestions on where to look. The finished prints look as good as one would expect from a machine like that, it is just the infill that is ra

After switching steppers on my repstrap build, the infill on a 20mm cube look odd. (I stopped this print after approx 5mm height.)
Sliced with cura on pretty standard settings. But yet, notice how the infill lines are cut open.
Any easy explanations?

I am considering making myself a small 3d-printer, something that will fit on my office desk. I already have some larger machines at hand, but a tiny one could be fun. Something with a build area of perhaps 10x10x10cm.
I would prefer a Cartesian XY machine where the printbed moves on Z. And of course, since we are here, a print-the-most design, would be nice as well.
Suggestion for designs I sh

I miss two safety features in the teacup firmware: (don't wanna see a meltdown here)
Something like Marlin's HEATER_0_MINTEMP Dual thermistor, measure difference between them
If thermistor reads below, say 5C, or two thermistors does not read approximately the same : shutdown
Without having much to back it up, I think the first one should be super simple to implement. The second one might requi
