General Mach Discussion / Re: best monitor size

« on: October 08, 2010, 11:27:05 AM »

Mark,

I use a 17" but I could manage OK with 15" if I had to. In use I am quite close to the monitor so size is not really that important.

Don't know if this is any help.

How about something like this ?

Hi Dar303,

As you say amazingly similar machine construction. Machining the ways and screw mounting pads prior to fitting the rails etc solves the welding distortion problems and is a lot more professional than my approach of using shims - keep up the good work. 

I look forward to seeing more pictures of your progress and completion of the project. Your PIC controller sounds very interesting and could be just what I need for my Synrad.

Thanks for sharing your information.

If this Guy ever builds his own CNC machine I would really love to see the pictures.

Just guessing here but it is probably your PSU - some PSU's need a load on the output to provide the feedback for voltage regulation.

Do you have any data on your driver board ?

I would try 5 Volts and see how you go. Only increase the voltage if you really need more torque.
(the 12 Volt output from the psu is quite low current compared with the 5 Volt).

Yes please David. We all like pictures here and I think it goes without saying that we are only too pleased to help you if we can.

A PC power supply would be fine. Steppers are usually driven at up to 5 times or more of their rated voltage (the limiting factor would probably be the insulation breakdown voltage) what must NOT be exceeded, however, is their rated current. (The voltage is generally increased to provide more torque).

Sorry, You are or course quite right, but it is a bit like logging onto the Harbor Freight site and asking questions about Grizzly machines.
