I use purple to clear Elmers washable school glue and it works really great, dunno whatcha talking about :) For printing with Nylon 618 or 645 I use a bed temp of 30c and find that I have almost zero edge curl and never have a problem with adhesion. The same very low bed temp works really well with...

Fine with me, I can wait.

Wow- Norway is a bit out there, considering these will be shipped out from the UK to the US and then back out, but I'm willing to do it! It would be roughly $32 american dollars though unless I can find a cheaper shipping service. I'm probably just about ready to buy some 15 of them, anybody else? ...

If you go through with the purchase, I'll take a set, shipped to Norway.

Are you able to isolate the gcode that causes it? Could be jerk/accel that's buggy. There are a number of fixes in 0.90alpha, but I don't know if this particular issue is fixed.

- Karl

I can't remember any particular gotchas when upgrading.

- Karl

Good news! Roland acknowledged the bug and applied my fix with some modifications. As mentioned, the bug exists in 0.80 RepetierMAX as well, although I'm not sure that's being maintained any more. My printer is down for a PSU replacement. If I find time, I'll take a look at your issue, Gene. - Karl

I learned three things. 1. TERNARIES FOR ALL THE THINGS! 2. Whitespace is where nightmares come from. 3. Constants are for pussies. Umm, yeah. I'm a professional developer as well, and I'll have to agree. :) I'm not going to criticize free software, but the Marlin code is cleaner. Have you had any ...

Thank you for your help! I can reproduce this with pretty much no load, ie. I retract the filament 15cm out of the hotend and just freewheel the filament inside the bowden. Higher speeds should increase the likelihood of skipping, but if you don't get skipping, you should at least get a good thunk o...

Retraction is most definitely still there. The direction of the extruder stepper motor is set in p->dir, while the axis_diff is the length of the move, at least that's how it works for the X, Y and Z axes.

- Karl

Nobody? I have a verification that the fix works from someone outside the forum, but I'd really like some more testers before I start pestering Roland.

Here's the 0.90alpha code. This is not a change in Configuration.h, this is a change in motion.cpp. Either you use 'patch', or you have to locate the code in motion.cpp and make the change there. Line number 1100. diff --git a/src/ArduinoAVR/Repetier/motion.cpp b/src/ArduinoAVR/Repetier/motion.cpp -...

I think I have it figured out. There appears to be an bug in the extruder code, where a quick extrude + retract with no simultaneous movement will ignore acceleration, ie. it will run the filament down at full speed, and then back it out at full speed with no decel/accel in between. At least for me ...

As an aside, I'm hacking on the Repetier 0.90alpha firmware. It's grown a little, and I'm having some minor issues. If I switch on the generic thermistor tables and sdcard support at the same time, the Arduino refuses to run. Remove one or the other, and all works fine. Am I hitting a size limit? On...

Forgot to mention, you need to run it twice. My bad.

I have an issue with the extruder skipping during a print. I've tweaked acceleration and extrusion speeds, but it still skips during this particular operation. At the moment, I'm looking at the source code to see if there might be a bug. However, it could just be my extruder or stepper motor is faul...

Gene: Roland pulled (as in "accepted") my fix today.

Gene: I sent a pull request on github. I'll let you know if it gets picked up.

There's a bug in the code for the generic thermistor tables. After fixing, everything appears to function as expected. Patch: diff --git a/src/ArduinoAVR/Repetier/Extruder.cpp b/src/ArduinoAVR/Repetier/Extruder.cpp index 4d481f6..3cd6fb7 100644 --- a/src/ArduinoAVR/Repetier/Extruder.cpp +++ b/src/Ar...

Similar issues here. After a couple of failed prints, I have resorted to always printing from SD. No issues after that.

I have a similar issue. Sometimes the MAX will annoyingly just shut down mid print (printing ABS), typically after half an hour. Flipping the switch fixes the issue, but the print is obviously ruined. I have to double check that it's a Logisys, but I got the kit three weeks ago. Initially I thought ...
