Re: Prusa i3 ruining my life - 9 years ago

There are no bridges there. I'd say the travel speed at 30 is way too low; gives too much time for nozzle to drain (esp PLA). Also looks like retraction is turned off. Need to be on; I'm using 2mm at 20 mm/s.

Re: Problem Prusa i3 Dual Extruder Replikeo - 9 years ago

I personally started with a single extruder (non Replikeo) for the exact reason of not wanting too much to go wrong.

Try moving X from the lcd panel.

Re: Walls grow higher than infill? - 9 years ago

The infill is absorbing the excess plastic, so it is not building up there.

Re: Edges of recengular shapes are OK, but circles are disaster - 9 years ago

Did not see the different Z heights. You are right, it is changing. Almost certainly something changing heights in a regular pattern, like the heat bed. This would be easily visible on the lcd readout. The holes however are in regular positions, so likely that the infill at those locations is affecting it.

Re: Weird Layer Shifting - 9 years ago

Also being only one direction in the Y, it might be a binding of the motion in one direction.

Re: Saving a print half way through... - 9 years ago

Nice. I've also heard of people super gluing the piece down.

Re: Prusa i3 - Filament jams, reverses during some prints - 9 years ago

I have slic3r and marlin and SD card, and sometimes my extruder would start off in reverse. Solution was to reset the controller board before every print.

Re: Edges of recengular shapes are OK, but circles are disaster - 9 years ago

Really looks like extruder temperature variation causing more flow as the temp raises, then less flow as the temp drops, and when temp is lowest, there is the least flow and you get the holes.

Re: Ripples on X and Y axis - 9 years ago

Also a chance that it is extruder temp variation.

Re: HIC Prusa i3 Stops Extruding Mid-print - 9 years ago

Sounds like interference in the cables going to the SD card.

Re: Random Movements - 9 years ago

I just had this problem, and just solved it. It's noise getting into the SD card ribbon cables. I put a ferrite ring around the both the ribbon cables (together), and the problem vanished.

Re: Prusa I3 skipping steps later on in my prints - 9 years ago

No, but sending too low power might.

Re: Retraction problem (not retracting)_Prusa i3 - 9 years ago

I do it in Slic3r here: Printer Settings > Extruder 1 > Retraction > Speed Retraction acceleration is in Marlin; mine is set to 3000: #define DEFAULT_RETRACT_ACCELERATION 3000 // E acceleration in mm/s^2 for retracts

Re: Pause after bed heat - 9 years ago

M190 S Does this mean that you would not put your desired temp in the start code, but would put it in the slicer settings instead?

Re: Infill doesn't support top layers - 9 years ago

Try retracting more.

Re: Retraction problem (not retracting)_Prusa i3 - 9 years ago

I had to slow my Wades retraction down to 20 mm/s or else it would vibrate and not move.

Re: Weak infill - 9 years ago

Also try setting all the advanced settings to 0

Re: waves at one side on object - 9 years ago

Also it looks to be after a travel across that open gap. So maybe retracting more before travelling will help.

Re: It's just too cold! - 9 years ago

Also could just get a portable floor heater, and point it at the printer.

There is a good youtube video of the slic3r settings.

Re: Pause after bed heat - 9 years ago

I've always wondered which command had priority: Start Gcode, or the slicer setting. I guess the Start does.

Re: Seam position settings - New option - 9 years ago

Also don't forget you can make it retract on layer change, which will reduce the seam.

Re: prusa i3 extruder issue - 9 years ago

Try 1000. Your motor gear might be slipping on the filament and not grabbing it.

Re: MakerFront i3PRO - 9 years ago

Looks good. I wish it were available when I was searching because there were no i3 steel kits available in the U.S. then.

Re: Prusa I3 - 9 years ago

Quoteyou mean metric threaded rods vs ACME leadscrews Yes. At least, 4-start leadscrews. They rotate down by gravity when the Z motors power off.

Re: [Update] Testing motors - they hum but don't move - 9 years ago

Disable the steppers and move it by hand. If if moves easily, then the problem is the drivers. Try plugging the motor into a different driver.

Re: Dual Z drivers setup in firmware - 9 years ago

I see... using dual drivers and endstops allows both Z to be homed. I guess that's why I like threaded Z rods, because they don't lose position when powered off, and I have not had the Z's get out of sync ever.
