    >>The TMC2100 input is still full step, 1/2 step, 1/4 step or 1/16 micro stepping externally, but internally it uses Interpolation and generates 1/256 microstepping

    This is how is achieves its “quietest Pololu compatible stepper motor drivers” status <<

    a 200 step-per-turn motor would be 360/200= 1.8 degrees per step. a 400 step motor (like we use) would be 0.9 degree per step.

    http://reprap.org/wiki/TMC2100 might also provide more information about how to set the hardware to 256 microstepping to match the software setting.

    My experiments have shown that 16 steps with 0.9 are right in my case…

    The machine is very quiet and does what it should do. 🙂

    Hm. I was just about to release an update. I guess I’ll have to investigate. Is there any error in the log.html file?

    Joram,

    – connect robot
    – open settings
    – change size
    – close settings
    – DO NOT DISCONNECT
    – open settings again

    are the numbers wrong?

    I’ll do it tomorrow. There is one more thing. I can not write any text, then the machine will pip and do not print.
    Tomorrow I will make a clip for you.

    When the machine beeps, look at the LCD. it is probably telling you to change pens and click the button.

    Are the numbers still wrong? Your last two posts did not answer my question.

    Ok, this makes the search area for the bug much smaller. Thank you.

    If you found some bugs and fixed the program, I would like to check / have the new version. 🙂

    Hi Dan, I do not know if that helps – when I start the software, the settings are as they should be.
    If I press “connect”, the presets are lost and the program does not know how big the Makelangelo 3.2 is and jumps to the settings Makelangelo 5.

    Hi Dan 🙂
    I have not used the machine for a long time. „start at line“ does not work. 🙁 🙁
    That’s a big problem for me.
    Do you have the intention to offer a new version?

    It is even worse. The program has 669,642 lines.
    If I want to start at line 200,000, it will not work.
    If I want to start at 300,000, it goes 🙁

    If I want to start at line 200,000 or less, it will start at “0”

    Um…. is your drawing a single line? The code looks for the last pen down command before the line number in question. so if you say “start at 200000” it looks in the file at 200k, then backs up until it finds a pen down command, then goes from there. What I can do is add an option to say “exactly from here” or “last pen down command before this”.

    So here’s the challenge…

    If I say “start at exactly this line” AND there is no pen down command THEN the pen will go there and wave around in the air until a pen down command is found in the gcode.
    Which could create a gap in your picture (missing lines)

    If I say “start from the last pen down before this” AND your whole drawing has no pen down THEN it will start at the beginning of the drawing.

    If I say “add a pen down command here” it might not be what you want! Maybe the first line you asked for exactly is actually not a “draw line” command.
