Need assitance from CNCPRO > EMC2 Camtronics board

Hello to the group and sorry my first post is asking questions.

A failure of my old DOS PC has prompted an effort to move to more up to date control software. So I have installed EMC from the latest live CD and have EMC2.4.6 and Ubantu 10.04.

My initial sticking point is the machine information and completing the step times etc.

The stepper controller is circa 2000 and consists of 3 Camtronics 5 Amp Chopper drivers, as they arePIC based boards I do not know the minimum times the pins have to be high or low?

I am assuming this is what the initial setup is asking for, i.e. the pulse length needed for the board to recognise it?

So I am wondering if any other users have these drives and could let me know what setting they use, I could start at 10 ms and work down but I need to keep moving the PC from desk to workshop so would like to get as much done before shifting everything.

The mill is only a small benchtop Chester Champion Mill converted many years ago.

The steppers are 3 x HY200 3437 400A8 I believe these are 300 oz in max. The mill never goes very fast with around 250 mm/min for G0 travel and typically 100 mm/min for cutting speeds with the 1/3 Hp motor and 1600 spindle speed.

Original page of the CNC setup from many years ago is www.tamarisktechnicals.com/pages/cnc.html which should be removed soon as it is so out of date now.

Anyway TIA.

Hi John.

I did quite a bit of searching before asking the question, the only post I found was regards screw cutting when searched for Camtronics.

I emailed the company but did not get any information, perhaps I asked wrong.

Also if I may? I searched the case studies on the wiki page and looked under mini mills to see any near examples but found most of the web pages listed were just broken links. Who should I mention this to?

Cheers

Adrian

p.s.

Nah The steering wheel is on the correct side! Glad you like it, off the road at the moment in a paint shop!

Hi Andy

You just said the wrong thing there in that you are in the UK so I know who to pester for answers:)

On the gear, I never thought about it with my manual mill. I believed the power driven ones had ball screws and driven gears on the opposite end to the handle, making them ideal for change over where as mine is standard lead screw. It could be something I consider in the future, where are you locate?

Cheers
