Ah, by knowing what to look for one can find the mark.
Excellent work! Should result in very nice prints.
Could you please tell us all points you have changed and where you have changed them in firmware?

Congratulations !
It really looks great, and smooth !
But I would not say X-axes is the one motor, Y-axes the other. Movement only in one direction, lets say x, is always a superposition of both motors because of the curved trajectory. Still I did not understand the axes direction. Here´s a (very) simple sketch...so it´s direction is like on the left side (1) ?

Oh yes,, the motor orientation and coordinate system offset is also strange...
Did you found out whats the 1600 ? Might be steppers steps/rev times the microstepping factor ?
Oh, and I forget to tell you that I love your rigid mechanical geomtry!
I think that´s the correct way to build a proper machine !
Would you mind providing further details about your machine and electronics?

Hi,
in ttsalo´s thread
he wrote about his "...reduction drives (1:25 in the current design)...", so 25 might be safely assumed as the gear ratio.
BR,

Hallo Zusammen,
wirklich schönes Projekt hier!
Gibt es eigentlich etwas neues was das Implementieren der inversen Kinematik betrifft?
Bezüglich analytischer Darstellung habe ich auch soeben den Bleistift geschwungen, von der Formel her könnten wir das einmal abgleichen (natürlich nur wenn Bedarf besteht!?).
Die SCARAs finde ich auch Klasse und habe auch schon rumgesucht, was es so alles bisher

Hello,
I hope it is Ok for asking a similar question in this Thread !?
My name is Mike, I live in Germany, 29, and still do not (yet ;-)) have a Reprap machine.
I was also thinking about using a SCARA geometry, just like "Evil Monkey" (EM) writes about in here:
The principle scara geometry is very interesting and there are only few parts that move, increasing reliability (at least I think so)
