Rotary attatchment

[PeterB]

Hi guys does anybody have any tips on using the rotary attatchment, I need to raster a round badge 80mm diameter onto a pint glass, the diameter of the glass in 93mm, I have tried various pulse settings but I keep getting an oval shape, I haved tried it on a 70mm diameter bottle an it was perfect, the rotor attachment does really seem hit and miss.

Regards

The chuck type is like this:

Rotary System Parameters Setting Instructions
For Chuck Style Attachment
We are using the Chuck rotary device on our laser engraving system. We have a cylinder
in the chuck. The chuck spins the cylinder according to the center axis of the cylinder.
Measure the diameter of the cylinder before you engrave on it. The result calculated
according to the formula is the pulse of the Y direction.
Calculation formula:
Pulse Y = D / 3277.647
D: the diameter of the cylinder (measured in millimeter (mm)) surface to engrave onto.
Example:
The diameter is measured as 78.74 mm .. This is easy to recognize as about 3.1 inches.
(78.74 mm) / 3277.647 = 0.02402
.. answer is 0.02402
You should go to the LaserCut 5.3 software... This value of 0.02402 needs to be set into
the parameter of the software "Machine Settings". After the value is stored into the YPulse
value, then press “Save”.
You then need to use the "Download Manager" to "Download CFG". This will set the
motion controller to use the new value for the rotary chuck.
*Remember: After you are done using the rotary chuck.. Remember to change the YPulse
back to the original value... This will be needed to use the standard honeycomb
table.

Many thanks for the reply, I didn't realise there were different types of rotors, I have a laserscript 6090 and the rotor is a machine with two rollers on and the glass fits on the rollers. I couldn't get the calculation to work for this type of rotor.

Hmm, I am not sure then! I have the chuck type, though I would like the dual roller type. Tried the Rabbitlaser site? Give HPC a bell, they should know.
