Wow this is a very slow group now it is

Years ago when I was first here we would get 200 or emails a day on stuff going on in the Home CNC stuff. I come back and we are lucky to get 1 email in 2 days Oh well. Is there not some get together coming up soon on CNC stuff I thought it may be in Michigan some where. if so when and where I would like to go.

Up Date:::: I have decided not to get the steppers right now ,Why years ago I was able to get 9 complete servo drives and motors , Jon Elson was able to look at them to see if they would work ,he said yes but the cost of it at the time was a bit much ,Why you ask because at the time the Canadian Dollar was only worth 0.55cents USD so other things came first .Yesterday I took them out of the box and started to look at them 180oz continuous and 584oz peak .Call up Yaskawa and found out that the drives with them are a stepper type servo drive and will take a signal right from a printer port and also from EMC program all they said I should do is hook them up thought a breakout board. So lets see I have a bunch of drivers and motors that work and by the looks of things I just need a board to make them work so that's what I am to do .

I will using the encoders that are on the motors but I was thinking of adding glass scales in to the system to give a better feed back on where the tool is at all times I have a bunch here but they are a larger scale I was on Amazon and found a few scales from China that are.0001 and thinking I would get them.

I believe that EMC will be able to get the information from them. But depending on how far the encoders are reading on the motors I do not know if they are .00005 or less I am thinking that if the two are not the same in reading they may not work.

I will have to read up on this on the EMC manual.

Now Dan do you still sell that RPM board that will hook up to EMC if so how do I order them let me know off group.I am going to hook up the DC motor I have for the lathe and mill so I want to able to control it from EMC as I am at it.

Now as for timing belts and gears I can not remember what we should use for size I was thinking I would use a 1 to 4 ratio so if the motor has a 1.5 "OD the one on the ball screw will be 6" is this about right or am I way off on this thinking..



Yes I know I am blabbering on but what other way is there to brain storm. and get other people's input on the thing
