@droftarts It is just normal, as our first planetary SG will be printed with a Duet powered printer... somewhere in the future.

Last question about "S" and "T" parameters from M669, how I can configure then?

You can configure them using M669 regardless of that kinematics you have selected.

@xXJRUSHMANXx said in POLAR PRINTER:

So, It's correct M669 K7 R100:400 H100?

That's correct if your radial homing switch triggers at radius 100mm.

@xXJRUSHMANXx said in POLAR PRINTER:

If I have TB6600 drivers configurated by micro-stepping, I understand that I no need Snnn and Tnnn (segmentation), true?

Segmentation is always used when polar kinematics is selected. You can omit the S and T parameters to use the default, or choose them yourself.

In a sample, you don't have M208 for Z axis. I think that its necesary here.

Yes, you should use M208 to configure the Z axis limits.

About the interface, I don't khnow softwares that can manipulate "donut_print_zone", should I send Gcodes manually (in cartesian coordinates)?

For normal prints that don't have a large hole in the centre on all layers, you will need to offset the print so that e.g. all X coordinates are at least +100mm. You may be able to configure this in your slicer. Alternatively, use G10 with parameter L2 to configure a workplace offset, and put this in your slicer start GCode.

Okey, to begin with a big thanks for your attention!!!

My next questions about polar kinematics are:

How I can define the rotative-origin of the rotative axis (≈center of the bed)?
It's my biggest mystery... In polar we have max and min radius, and the center is in the middle.
But I have my min_rad at 10cm from my real rotatory center and max_rad at 30cm from it. My case is a donut work zone (or just part of it, 90deg for start )

In the rotative axie, where do we use mm and where degrees?
In config.h there is only mm (ej: M566, M92) so I can understand that in M208 we should to write Y__mm instead of Y__degree.
But at the homing files we are working at degrees.
So I need to calculate mm from degrees? How I can take step/mm for rotative axie?

If I use external drivers, should I use M350, M906, M84?

There is core files I should to check exept homing files?

Waiting for a response

Sincerely
