M92 Help

[Whiskey]

Hello (again),
try to finish my Morgan …
just a question:

in your calibration guide u wrote

1.8 with 16 is 107*1,25 for a 16 Tooth Pulley

I’ve a T2 belt with T2 Pulley with 20 teeth (18mm) 1,8° and 1/16

The calculator on http://calculator.josefprusa.cz/ gave me this for the M92 Command:
Result
80.00
Resolution
12.5micron
Teeth
20
Step angle
1.8°
Steping
1/16th
Belt
2mm

80 is right ? Multiply with 1,25 ?

Regards
Whiskey

I will have to see how i can incorporate that calculator into our process. Will make life a lot easier…

[Whiskey]

so the calc is right?

[Quentin Harley]

Have not checked yet. The idea is to get it close, and use the calibration routine to get the correct values.

Hi Q …

so – what is the formular ?

[Quentin Harley]

It depends on many factors… that is why the calibration routine asks you to enter it roughly, and then it is determined by the movement of the machine.

M360, M361 and M364 are codes designed to bring you close to where you need to be, and then adjust by hand until the condition is met (Arm parallel to platform in one, 90deg between arms in the other.

if M360 does not work, jig it by hand until it is in the right position, M114, and do the M206 step.
Then jog by hand until the arm is 90deg to platform, and take the reading as per the flowchart. This is the way to get the real M92 step values.
