Hello Irfan.
I bet your having a great time, no matter the doubts you can get. Keep going.
I like your solution to the limits switches. I was thinking in involving them in a very soft plastic to protect them from the powder.

No Hugo, I think the limit switches just need to be maintained, enclosing them in soft plastic may result in more dust accumulating within it. Any wayz if you have a proper dust evacuation system then there is no need to protect the limit switches.

Irfan & Hugo, all dust evacuation systems have a problem to work correctly at the edge of the board. When you are right on the end of a board, the cutter gets exposed.

Irfan, you have the right idea to lift a mechanical switch up, away from a flat surface where dust will collect. Also, the holes in the switch must point downwards (like you have it) so that the dust will fall out.

Hi Gerald and All,

I had a Q

1. for the timing pulleys which i will be using to drive the pinion can i use just the grub screws to hold the pulley's in place or is it necessary to have a key to bind it with the shaft.

2. If only grub screws can be used tehn how many, I was about to put 3 each 120 degree apart........is it OK

3. I expecting a center distance of 325mm, will that matter much?

4. I will be using a HTD 8 mm pitch belt. is it OK

Regards
Irfan
