I agree.  The dremel clone I have is variable speed but the torque available at the lowest speed (which is still fast) is too low so I end up jacking the speed to compensate.

So I was hoping to find something which was capable of reasonable torque at low speeds.  And preferably cheap to boot.

General Mach Discussion / Some guidance on spindles

« on: January 30, 2012, 06:18:38 AM »

Hi all,

I am in the throws of making a CNC router for use with plastics and was wondering what others did to power their spindles?  I am currently using a cheapo dremel equivalent which is running way too fast.  At the moment I am intending to use the machine on plastics.

Thanks

Thanks for the quick reply.  I was beginning to suspect the behaviour was normal and it was my understanding that was in error.  I will look into the soft limits.

Thanks

General Mach Discussion / Limit switches

« on: November 15, 2011, 10:40:10 AM »

Hi all,

I have searched around but have not found an answer (that I understand).

I am new to Mach3 and have built a prototype router and connected it to Mach3 via a 3 axis driver board using TB6560's.  The board has four inputs for an EStop and limit switches.  I have connected them up and the EStop works as I would expect but if I activate an axis limit switch it works exactly like an EStop.  Is this normal I expected it to just stop the axis in question and not all of them! 

Thanks, and sorry if this is the wrong place or a really dumb question.
