This is awesome. Thanks for the side by side comparison. The mesa cards really are a step above everything else. I don't need 72 I/O pins, but dang it is nice.
Great demonstration, thanks a lot . Where can I find details of making closed loop with printer port ? connection, HAL file example, etc. ? Thanks a lot
I'd love to know more about this board. I have a Unimat SL-200 w/ Guru Automation cnc kit on it. The controller (or motor driver board?) was intended for use with Mach3 over Parallel port. I never used any of that. I would love to move away from parallel port either using mach4 or LinuxCNC. I am totally new to DIY CNC stuff so while I've been doing a ton of reading it's easy to get overwhelmed.
Super cool … can you share or point me to a video where you share your latency number and maybe adjustments to your OS ?… more for curiosity. I started a linuxCNC system as a test bed using a Mesa card … seemed to make everything easier. Thanks for sharing your experience!
Hi! i need help, i buy an old emco pc turn 55 but, he comes without worm on the turret, e need replace it i, you can send the dimensions from the original?
Is tuning necessary when using a mesa card to send step/direction pulses to a servo drive? Seems like I wouldn't need the encoder feedback, but I'm not sure.
So I have a few questions, which Mesa ethernet card are you using? What is the CPR of the encoder? Looks like you are using the dual BTS7960 mosfet driver? I have used 5i25 and 7i77 on a conversion, but never thought that you could get analog output from the parallel port. I find this really intriguing. I have been putting off converting a CNC Clausing lathe because they never seem to have a Mesa analog card in stock. Curious if there is enough IO available for 6 encoders and 2 pwm drivers?
This is a 7i92 (ethernet interface). the encoders are 500 line - 2000 count. The servo drives are from amazon.. yes they are BTS7960. The servo drives are being driven by raw pwm (pdm) from the printer port. The analog out that I created for the spindle drive would not work for closed loop servo control - its bandwidth is too small.. (10 to 50 hz) perfectly fine for spindle control. Have you tried mesaus.com/ ? they are a re-seller.
Hey - on an unrelated question for you.. My dad was collecting parts to re-do his very rusty 2003 f350 superduty.. (replacement frame and cab and such). I am leaning towards taking on this project. I don't plan on doing much to the engine while being out - what are some things that should be replaced while the engine is out? The injectors were replaced a around 20k miles ago. Thanks!
no - not normally.. but I want to do some non-circular turning at higher speeds... Like czcams.com/users/shortsnViXP9SsdWc but faster... That I need high speeds and high acceleration...

This is mostly what I do... czcams.com/video/X2zXCQpHwOA/video.html

Nope - no real tuning needed that way.. (usually)

@@MakersEaseI am predominately a Dodge Cummins guy, is it a 6.0?
@@MotorsportDiesel Yes - I am pretty sure it is the 6.0 but I have not really looked...
Never need that sort of speed on that axis. Any issues with regenerative braking back feeding into your controller?
no - not normally.. but I want to do some non-circular turning at higher speeds... Like czcams.com/users/shortsnViXP9SsdWc but faster... That I need high speeds and high acceleration...
plus - This is really inexpensive hardware to make a really decent axis control. (the drives were like $5) and seem to perform just fine.
Great project man
