square rounded

I recently installed EMC2
I used stepconf wizzard to configure it, all works well, but when I draw a square the corners are rounded.
An idea on how to solve the problem?

Hello,

Take a look at constant velocity G64 and exact stop mode G61.
G64 (continuous mode)
G64 tells the planner to sacrifice path following accuracy in order to keep the feed rate up. This is necessary for some types of material or tooling where exact stops are harmful, and can work great as long as the programmer is careful to keep in mind that the tool's path will be somewhat more curvy than the program specifies.

Your acceleration setting has a big effect on this also.

I do not use the G64 code I use a simple test code:
GOX0.00Y0.00Z0.00
G0X100.00
G0Y100.00
G0X0.00
GOY0.00

When I finished installing I drew a square with sharp corners, now with the same code I rounded the corners.
thanks

G64 and G61 remain in effect until they are changed. G64 I believe is the default when you Start EMC the first time. There is a box on your screen that shows what codes are in effect...look for it there.
You can also enter G61 from MDI and try your box again.
Also if you run at a lower speed with G64 the corners should be better.

Thanks for the advice.
Wen I have a little free time I try it.

Certainly I will read it, but there is an equivalent in Italian language?

Hi Rick,
I'm a complete idiot with this please bare with my not-so-intelligent question.
Do you meant as long as I type in the G61, G64 or G64Pxx.xx code in the MDI box, it will take effect & superseed any future G-code files which does not contain any of the G61 & G64 code?

Thanks in advance.

Hello,

Yes G61, G64 will stay in effect until change by another G61, G64. You can enter them from the MDI box and / or you can put them in your G-code file.
