Hey gang, Ive been building a Momus design CNC for a while now and have run into a snag with the motors that Im hoping someone can help me with. Im posting this here mainly due to the fact that the Momus board doesnt receive much traffic and I wanted to get this in front of as many eyes as I can.
The problem Im having is getting my motors to turn properly. First of all a quick summary.
Drivers are the DM542A from Longs, Wantai or Leadshine take your pick
Motors are the 425oz/in nema 23
Power supply is the 36V 9.7 amp
PC is running Win XP SP3
What is happening is the motors are turning painfully slow. Im talking less than 2 IPM. Not kidding. No amount of settings in Mach has made ANY difference at all. I have tried every combination of setting that I can think of and nothing changes.
Now here is the weird part. If I only connect 1 motor at a time, no matter the axis, it will turn properly and rapids of over 700IPM are even possible with NO lost steps.
Its not until I try to connect more than one motor at a time that the problem begins.
I have read where this or a similar problem is common with this setup however I have yet to find a definite solution. Much speculation and many suggestions but no one has been able to explain whats going on.
If anybody has any idea or better yet a solution please do share as I am not the only one that has experienced this problem. Some explain their systems acting erratically along with the slow speeds but the slow speeds seem to be a common denominator.
Im looking at the power supply thinking its not doing its job but others have tried replacing it with no love. One person here at the zone posted they have found the problem and even posted a link to a Mach3 support article but the damn link is now broken!! AARRGGGGHHHHHHH!! LOL
I think the article was on Mach 3 optimization but other than that not sure.
Here is a link to my build thread if interested, comments and suggestions always welcomed.
