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.
better forget all mach3-4 software and USB BOB card, if want safety machine build need use REALTIME kernel and this is only linuxcnc software.windows not used ewer factory automation because not have safe and REALTIME, and OS have worst lot only blue sgeen and problems and accidents have big you health.
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!
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.
no - not normally.. but I want to do some non-circular turning at higher speeds... Like ruclips.net/user/shortsnViXP9SsdWc but faster... That I need high speeds and high acceleration...
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!
how make printer port closed loop ,what elektric board need, i have linuxcnc but no encoders, cheap 10$ paraller port board not have input lot, only 4-5 input have and all used, home SW, probe,E-stop. were can add encoders ????? and how need mdified all code file, hal, ini, etc, what have. mesa card have perfect all cnc but too expensive hobby users buy.

This is mostly what I do... ruclips.net/video/X2zXCQpHwOA/видео.html
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.
Nope - no real tuning needed that way.. (usually)
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 ruclips.net/user/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.

@@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...
@@MakersEasecould be the 7.3 or 6.0 in 03. I would do different things for either engine if i had it out.
