If I’ve seen it before! my answer is YES!

Changing a machine reference point is not necessarily obvious for everyone!

So on Polyoard will not do it!

First I would proceed in stages!

Silly question were the parts well put on the machine?

For a question of precision, can you try to make a small cabinet ang Profiling/Calibrating all parts, WITHOUT RETURN PART!
you can use the function, Oversizing on polyboard for your CNC Profiling all part

(It’s what i do all the time! BUT you need to find solution for configure correctly your reference point i you return part for second face!)

that will tell you already this is a problem of reference point, or a bad configuration internal to your CNC

Cheer, Alex

Hello Alex,

Thanks for the reply. Yes, there’s no problem on Polyboard at all. We think it’s all on the CNC reference point in which we think if we could change or set it on Polyboard.

Here’s an example of a problem that we encountered(see attached photos).

Have you experienced the same problem as this?

Hi Grover,

Sorry but I do not see any problem setting in Polyboad, and none in the file that you have attached that are exactly identical except the file name …

Do you control that the position of silk drilling has the right place as specified in Polyboard ?
for example in the left side.

If not, would there not be a shift in the origin of your CNC?

Cheers, Alex

Hello guys,

Is it possible to set the same reference point for these drilling coordinates(TCN file attached)? Is this possible to fix or to set on Polyboard so that all drilling should start in upper front of the panel or anywhere we want to?

Currently, as we tried to assemble our computer table, the left and the right side of the table drillings don’t seem parallel to each other for about 2-3mm difference but asymmetries are quite visible?

Has anyone run into the same problem as ours?

Best regards,
Grover
