Hi All.

I would say i am still new to CNC machines. I still have a 1m x 1m custom build machine which is belt driven that needs an upgrade when I have more space.

In between, to keep me occupied i bought a used CNC 3018 Pro.
The main thing I want to be able to cut is acrylic most likely no more than 5mm thick.
It would also be nice to cut some soft woods.

Before I get into the excitement of making my first cuts I want to do some upgrades, primarily focusing around safety.

My plan is to:
1. fit it with limit switches.
2. Get a probe - to set the correct heights
3. a probe to cut out if it ever hits the aluminium mounting plate.
4. a Safety cut out (which i know i can use a in series with a limit switch at worst).

I know the driver board currently has spaces for:
Probe
X / y / Z limit switches.
PWM Laser module.

1. What are the best small limit switches I can use?

I currently use Aspire to do the designing from which I can get a DXF. I then import this into LazyCam Mill to cut. (Right now it is dry running with nothing to cut.

2. I have considered Mach4 Hobbyist - Will this work with the 3018 Pro?

3. I haven't yet figured out how to control the spindle speed. Is this possible via the PWM Spindle connection?


4. What wouldn't you recommend to be cut on this?

5. Is there any other advice I can have for using the CNC 3018Pro?

Thanks in advance.
