Hi

hope this is correct forum for this.

i have problem with an machine "boarke BWM-S482AVD"
https://www.boarke-tw.com/product-DO...LE-CNC-05.html

seems it has Osai controller and drivers.

the problem is that one table cant keep up with the other table,
no fault codes in CNC panel. i can see that the position of the tables are in sync in the pc controll.(Y1 and Y2)
but one table moves little slower before position/or comes to position after the other table.

this results in that one table make oval holes in plywood and the other makes perfect circles.

i can not feel any slopp in the table, both are rigid.

what could be wrong? where do i start finding the fault?

of course this machine is from taiwan and uses boway-cam and some unknown software interface.
and support is hard to find!

i have had in mind to switch driver from one table to the other or switch motor, but this is far from my skillsett!.

hope any one can help! thanks.
