General Mach Discussion / Re: Delta VFD control from Mach

Hi Don,

You need to check with your VFD instructions but selecting US Mode on the C41,  I would connect both V-IN together and connect these to VFD terminal SD   then relay #1 terminal NO to VFD terminal STF   and relay #2 terminal NO to VFD terminal STR.

I've now lost all respect for you, my friend -

Hi Dave,

I have been having sleepless nights about this - Could I possibly redeem my position if I sent you some free samples of the 'infinite trolley token' and the 'car park entry card' ??

General Mach Discussion / Re: Steppers are too slow

« on: December 01, 2011, 05:15:46 AM »

Hi Stuart,

Can I suggest you carry out a couple of very basic tests.

Initially just one controller set microsteps (SW 5-8) at 1600 steps per rev and the motor current (SW1-3) at 3 Amps.

Go into Mach, Motor tuning and set "steps per" to suit your machine screw pitch (theoretical) then adjust motor velocity.

What speed does the motor stall at ??

Connect a voltmeter to your power supply output.

Does it maintain the 24 Volts during the above test ??

Ian,

Even if his system is not that well matched don't you think he should still be able to achieve better than 50 rpm ??

Tangent Corner / An Optical Illusion.

Obviously the camera shutter plays an essential part in creating the illusion here but I found it interesting nonetheless.

Hi Stuart,

The fact that you cannot use P2,P3 is an indication that something is wrong there.
One difficulty that has cropped up a few times recently is that most newer PC parallel ports have changed from the 5 volt TTL standard to the 3.3 volt TTL standard and some breakout boards will still only reliably work with the 5 volt signals.

Stuart,

I take it you have set up each of your steppers for optimum Velocity (reduced by some 20% - 30% for reliability) and Acceleration ??

Hey buddy, don't do yourself down, we have all been there - in my case many times.

There are a number of test programs which are below the 500 line limit here http://www.machsupport.com/forum/index.php/topic,18345.0.html these may be helpful in setting up and trying out your machine etc.

I have high degree of intelligence and speed problem solving.

Looks like you joined the right forum buddy, all the members here have a high degree of intelligence and speed problem solving, I think you will fit in well.
