Re: Latest Marlin on Printrboard: Problems!
Yes, it compiles for RevF, but FAST_PWM doesn't work. There's a PR to fix that already, and a big cleanup of all the AT90USB pin defs (finally !) coming down the pipe, which should make using the...

Hi everyone, I have been looking for a while for a Marlin to be able to assemble a two-axis X-axis Y-axis polyfan cutter The idea is to use a 1.4 + mega ramp with lcd and SD to be able to make it 100%...

Do you want to move both Y-axis completely independent? Do you want to cut airfoil cores from foam, where the profile on one side is the same on the other, but in a different scale? We used to make...

Hi, thanks for the interest. No, single parts 2d, a single motor-steper communicated with the two ends of the wire mechanically. What I need is to modify the menu section and screen presentation

Hello, Trying to debug my delta and trying to understand what is causing occasionally stuttering. Is there a way to detect line buffer underrun in SW? I can occasionally notice stuttering-like...

Late yesterday the AT90USB simplification/unification code was merged. Gone is the Marlin/FASTIO numbering vs. Teensy numbering. The new code does implement pins 46 & 47 for the two ports that...

Stuttering delta while printing arcs is a classic problem with 8-bit cpu. You can reduce the "segments per second" parameter and also the refresh rate for the LCD to free some cpu cycles. ( graphic...

Yep, exactly. I've been tweaking "segments per second" value, but I like to move on to have actual facts. Also determine how much LCD actually affects to this. I'm pretty sure I'm not the only one......

If you are running a Delta Printer... You should consider using a 20x4 LCD Panel instead of the Graphics panels. The Graphical Panels eat up a lot of CPU cycles. The 20x4 is pretty tame on what it...

Yep. I consider matrix LCD the only option for delta controller with 8-bit Atmel. If even that one is possible.

MKS TFT28 and MKS TFT32 displays are also good. Since they don’t put any load on the controller.

Hi Folks, I'm near the end of the build of a i3 MK2 clone and have run into a problem with the Z-axis motors. Specifically, the Z-axis will move down (and trigger the endstop) but it will only make a...

I made buffer logging and yes, buffer level hits to bottom pretty easily on arc moves. Even without LCD or SD. When it is human noticeable (stuttering) the situation is very bad. Some help can obtain...
