I just had a thought, that there are rubber preservative/lubricasnts available from auto acc. stores armerall the stuff you spray on plastic and rubber seals - should work fine. Which is cheaper "armorall "or "KY" decisions decisions.

General Mach Discussion / Re: Mach 3 Pulse Rates per axis

« on: April 01, 2008, 09:44:08 AM »

I am a bit short on memory (256Mb) in 1.7G dell computer. I will upgrade to 1Gb of ram when it arrives in the post - Might do the trick.

Hood, you may be right about the steppers being maxed - have not had any experience with what is the norm.

At this stage I can still get XY 7000mm/min and 1000mm/min Z  running smooth.

General Mach Discussion / Mach 3 Pulse Rates per axis

« on: April 01, 2008, 07:49:24 AM »

I am currently tuning X/A,Y and Z axis on my router. When I try to drive the steppers of each axis above 8000 pulses per second the motors sound awful. Around 7000 they are smooth.  Is this because Mach3 divides the 25000 pulse rate up between all axes?  So by increasing the pulse rate is it possible to drive each stepper faster than say 7000pps.

Just a thought,

Thanks, Hood
I just tried a smear of Vaceline on the new belts.  Now  whisper quiet.

Hi all,
Can anyone give some advice on lubricating: 1.  timing belts and 2. Rack and Pinions. Do they require lubrication?
My thoughts are that the lubricant would attract dust build up.
 Maybe some type of silicone spray may work?
(I have just spotted the other forum sub sets! I will use "Tangent in future" Thanks Bret)

Hi,

I really enjoy the discussion on this forum about Mach 3 etc. ,but is it OK to discuss other more general topics about building and hardware etc. on this forum?

I seems a shame to have to use another forum when we have a great group here at the artsoft forum.

I am just putting up a possible idea , maybe another branch on this forum site that deals with machine topics?

I hope I am not out of order here
