leadshine motor drives

[Charlie.G]

first I wanted to thank everyone for their help,
I was looking at all the choices that are available and for someone like me
who is a novice at best it can be overwhelming trying to understand all
this information.
from Gary's input I looked at some leadshine drives at the web site he recommended
I found a motor and drive "KIT" part # STS-H134-971 which is a 110v drive and 971 ozin motor 318.00 each
it is a few bucks more than using the DM870's but wont need to have a power supply.
then I looked into the servo option, the clearpath SDSK 3411S or the 3411P (same price)
with cables (50 foot cut in half) they are 426.00 each
so 426.00 x 4 =1704.00 for 4 motors
318 x 4 = 1272.00 for 4 motors so it is roughly a 100 bucks more per motor setup
for the servos there will be a bit more cost for power supply and misc. junk
so I am leaning towards the servos do you have a recommendation on which servo motors
to use?

thank you,
Charlie

Some people are using the closed loop steppers like this. https://www.automationtechnologiesinc.c ... 128-oz-in/

Gary,
thank you for the help....ken as well there are photos of my machine in the gallery if you want to see it...
I will look into the stepper motors as well is automation technologies a good place to source these parts I
believe I read that their motor drives were rebranded leadshine??

thank you,
Charlie

Where are photos of the machine?
Why do you want to replace the 203v's?

Marty,
I want to update the machine,
I am under the impression that I can improve it by
replacing the motor drives and motors...
maybe I can get smoother cuts?? by being able to microstep etc.


here is my machine viewtopic.php?f=57&t=2469

thank you.

Are you having trouble now? The G203V is a microstepping drive. Did you chose motors according to your torque needs and also choose the correct power supply voltage?

Are you using smoothing? In Centroid CNC12? What CAD package are you using?
Just trying to understand why you want to upgrade (other than Gary doesn't like the Lizard)

Marty,
there is no one thing that makes me consider this,
I value Gary's opinion but I am not doing this to please him.
it all started with changing the pull up resistors on the gecko drives
and going to the db 25 connector set up and adding the relay board, then I looked at the control box
and figured that I wanted to rearrange my setup to make room to do this. I want to change where
the fan or air exits the box want to get it closer to the top, I wanted to change the way the drives are mounted
in the box and a few other things, and while I was going to tear everything
all apart I thought it woud be a good time to update everything.
the other reason is the machine is in my brothers metal fab shop,
I have access to all the equipment etc. I need to modify whatever I want
on it right now. I have my house up for sale so I have a limited time to access
the equipment to make modifications. when my house sells I will be moving to the gulf
and I am now located in Minnesota.
maybe that isn't a good reason to do this?? if I won't gain much then the answer is NO it isn't worth it
so do you think I won't gain enough to warrant the upgrades?

Gary, if you read this I would like to purchase your low profile db25 breakout board from you if I could.

Are you having trouble now? The G203V is a microstepping drive. Did you chose motors according to your torque needs YES BEEN RUNNING THEM FOR 6-7 YEARS NOW and also choose the correct power supply voltage? YES I HAVE AN ANTEK 600 WATT DC POWER SUPPLY WITH A 54 VOLT 12 VOLT AND A 5 VOLT OUTPUT

Are you using smoothing? In Centroid CNC12? NO I TRIED IT BUT IT DIDNT MAKE A DIFFERENCE ALSO RUNNING 4 TO 1 BELT REDUCTION THERE IS 0 BACKLASH AS WELL What CAD package are you using? VETRICcolor=#FF0080][/color]

Marty any input you have I am happy to here and thank you for your help...
you are the reason I went to centroid I ran across your videos on youtube.

I can understand the desire to clean up the cabinet. I recently did this on my 2x2 Phoenix Router. I did replace the old DC brush servos with new smaller AC servos.

Personally if its a working system, I am not sure what you might gain. But if you want to go through the effort and expense, AC servos. Clearpath SDSK,
Hybrid Closed Loop steppers then. If you go that route, do create post on the outcome.

Charlie...
I am with Marty on this one in wondering what you feel you might gain. I've been on the MechMate forum for about 10 years and am familiar with the build. Here are my thoughts.... worth .02 or less

Biggest improvement to cut quality would be to add linear rails in lieu of gravity based Vroller system on (usually hand ground) V rails
Next would be to add more mechanical reduction (5 or 6+ to 1) with smaller pinion
Next would be use higher voltage AC or DC drives Stay away from the 1/10th microstep setting
Lastly would be to add larger motors, as a spring loaded pinion will jump the tooth when too much torque is applied.

Gary, Marty,
thank you for your advice, I will look into your suggestions.
I was just waying out options as I enter into redoing my control box.
do you have a suggestion on which reductions to use?

thank you,
Charlie
