I'm glad! If you get stuck, send me an email and if I have the time I will be glad to help you out.

Hurco vm2 will retrofit,but still conduse about what mesa card will using, Have swap arm atc,

I got a bit sidetracked as you will see in MESA 5-Axis #4... but I'll be doing more with the MESA in future videos.

@@Askjerry great to know 👍In case you'd be running out of ideas 😋 I'd gladly be helped by a video about encoders (linear/rotary, incremental/absolute) feedback setup... Have a great day and new year's eve

@ Actually... I did at least cover part of your request here: kzfaq.info/get/bejne/i7RokseG2am2YZ8.html Linear and Rotary work the same, the only difference is that the rotary has the slots/stripes around a circle and the linear is just a long strip of stripes typically printed on glass or plastic. Quadrature encoders are the type used... they have a repeating pattern of four states (quad) that can be read. You keep track of the count to know position. Absolute encoders use one track per bit... so you would need 4 tracks for 16 possible positions... 8 tracks for 256 positions. If you had 16 tracks, you would have 65,536 positions... which sounds like a lot... but if you had a 5-start ballscrew where each rotation was 10mm... you would have a travel of only 10mm... with a 10:1 pulley... still only 100mm. And... an absolute encoder with 16 tracks would either be very large, or very expensive. A high accuracy incremental (quadrature) encoder is about $90. The same type in absolute, 12 bit (4096 position) is $283 from the same manufacturer. usdigital.com Stepper vs. DC with Encoder - The DC servo has the advantage of positional feedback... so if there is an error (something stopped the movement) the computer would know. With a stepper, if it misses steps... you just do not know. The encoders take more to set up... adjusting the gain, the delay, a PID loop... determines amount of change... and if the motor is keeping up or lagging to control current. In practice with my mills... I have had no problems with the steppers. I test them to see how much they can handle... then never go beyond 2/3 of that limit. Since the modification of the Monster Mill... i have had no issues. Absolute Encoders - Good for a single rotation to determine a repeatable angle with no initial calibration needed.. what you read is where you are at. Incremental Encoders - Less complex, great for multiple rotations. Need to be initialized to know where the starting point is. Stepper (No Encoder) - The stepper acts as a physical encoder as long as it is not pushed hard enough to loose steps. Needs to be initialized to have a known starting point. Does this help? Jerry

Instablaster.

I appreciate that. Today (December 16) I just finished my project in Atlanta... and I'm home here in Austin until at least January 2nd. (In theory) So I'm very hopeful that I can get some more videos created and do some more projects. (Fingers crossed!)

You are welcome. I'm sorry if the section on opto-couplers was confusing... let me attempt to clarify. If you are running the MESA with 24 volts, which is typical... then if you have the 7i76 for example, and you have an output... it will switch from 0 volts to 24 volts. Imagine now that you want to turn on some 5 volt device. POOF right! So we take the 24 volts and drop it down with a resistor to turn on a tiny LED in the plastic chip. On the other side of the chip is a transistor... an electric switch if you will. We connect our 5 volt supply and device... and it gets switched on and off. With the 24 volts safely on the other side of the 4N35 chip. Additionally... say you goober something up big time... connect 120 volts to the chip... well... the chip will be destroyed... but the opposite side is protected up to 4000 volts. So you save that expensive MESA card and the computer. The 7i76D

@@Askjerry Thanks Jerry, you are the coolest. My project is a Hurco KMB1, DC Servos and 5.5 HP 3 phase spindle. In many respects it is similar to your MONSTER build.

I have not. There is a lot I would like to do with the Mesa card but haven't been able to do so. I have a PUMA robot that an idiot friend destroyed the main cable, so I need to build a new controller. All the motors are DC Motors with Quadrature encoders... so it would be a perfect start. When time permits... I'll get that done.

Yes I understand this. Some of my audience not so much. But they should get the general idea... The hot side is dangerous. :-)

**Facepalm** There is always one......Where do you find 120v with 25 mA ???? anytime you have 120V you have enough amps to kill you...

Actually 120v with low amperage "can" kill you. You don't want that no where near your heart or brain for example. 120 volts and 100 milliamps can pass through your heart and give you a heart failure. Google it. While it is true that high amperage kills, but it is false conjecture. Tell us why a 100 AMP car battery with 12 Volts does not kill you? Its because the force of 12 Volts is not great enough to pass through your skin. Hope this makes sense.

From what I was reading... " The 7I96 is a Ethernet connected motion control interface designed for interfacing up to 5 Axis of step&dir step motor or servo motor drives. Step rates up to 10 MHz are supported. The 7I96 also has 11 isolated inputs plus 6 isolated outputs for general purpose I/O use. A high speed encoder interface is provided for spindle synchronized motion. A RS-422/RS485 serial expansion port and a parallel expansion port." It appears the stepper section is wired the same, but there are only 6 outputs instead of 16 that the 7i76D has... and only 11 inputs instead of the 32 that the 7i76 series has. Not sure why you wouldn't go with these LAN variants... store.mesanet.com/index.php?route=product/search&search=7i76e

Thanks, I added some text in the description to let people know.

@@Askjerry Thanks! Your video was very helpful in getting me up and running. I appreciate the time it takes to make these videos!

I pulled up the manual: www.mesanet.com/pdf/parallel/7i93man.pdf And it says that the board can be configured for STEP/DIRECTION (PDF PG 5) On page 15 (PDF PG 19) if you configure the board for SVST8_4IM2, which will give you a 4-Axis stepper motor configuration. The SVST4_8 configuration will give you 8-Axis stepper motor control.The unused pins appear to be encoder inputs and/or GPIO. Other than that... all i can say is start reading: forum.linuxcnc.org/forum/search?query=mesa%207i93&childforums=1 Good luck! Jerry

I have not done a project using the Ethernet version of the MESA card so you would likely need to go to the LinuxCNC forum to get that information. Inside the computer I used, there was an Ethernet and a USB, but also a PCI card slot. If you have the slot inside, then you simply get the mother/daughter board combination, plug in the mother board, and attach the daughter... and you are done. As for the Ethernet version... it can be found here. store.mesanet.com/index.php?route=product/product&product_id=343&search=ethernet More information can be found on the forum: forum.linuxcnc.org/forum/search?query=7I95%20Ethernet&childforums=1

@@Askjerry Thanks. I found the info. it's board 7i92. I guess I should have said keep my same c10, kelling 5056 steppers and 290 oz motors hook up.

@@jasondevault5066 Ok... sounds good. Manual: mesanet.com/pdf/parallel/7i92man.pdf Store: store.mesanet.com/index.php?route=product/product&product_id=302

You can also use the 7i76E/ED. It runs off an ethernet cable. You choose the E or ED version depending on the type of outputs you want, Sourcing/Sinking. See pages 1 and 17 in the manual. It runs up to 5 axis of steppers or servos plus spindle. Some of the I/O can also run an MPG as well. The configurations are similar to what Jerry did in this video. It is fully expandable but already has quite a bit of features. Someone else did a video a while back and he ran it off a laptop with a real-time LinuxCNC kernel. The machine was flying. Pretty cool. If you get it running on that Gigabyte brix mini pc, let us know how the speed is. I was looking at the Intel NUC's or even the RaspberryPi 4 for this purpose. Another option is the 7i96 but it only has 11 inputs and 6 outputs. Great video Jerry! Nice work.

Я сожалею. Я думал, что они у меня включены. Позвольте мне добавить субтитры для вас. И спасибо, что сообщили мне об этом!
