User Manual for the THC Isolated ADC available now.

[phil-barrett]

V1.0 of the THC Isolated ADC manual is now available.

Feedback, suggestions or corrections are greatly appreciated. Either here or on the THC Isolated ADC github page.

Also, I still have a few boards available.

Hello,
I write one month later, do you still have these THC boards ? Do you sell the breakboards as well, and hopefully thus ship them together ?

[phil-barrett]

Yes, I have a couple. $20. And yes, I still have the breakout boards. I can ship together, no extra charge. Make a note in the tindie purchase (special instructions) - say ADC and Toutoune86 so I can connect the order to your post here.

You can pay the $20 via paypal separately from the tindie transaction (I haven't put it as a tinde product yet). I will send instructions after the tindie order. Should not take much extra time but ping me here as well - tindie has been recently having some email notification problems.

Hi Phil,
Do you have any of the THC ADC boards still available? I would love to purchase one along with the breakout board you have on tindie. Ive been looking on tindie but have only successfully found the breakout board.

Thanks,

Dana

Yes, I just got a small run of the final version in. I've had a lot of work to do lately but will be putting the ADC boards up on Tindie. They will be priced at $29.99 USD through Tindie. (The ADC chip is annoyingly expensive for what it does.) I still have a number of things left to get the board up on Tindie so I'll sell direct to you for $20 USD. US Shipping is$5.50, contact me if non-US shipping. If you order a T41U5XBB on Tindie, I will ship them together and save you the postage. You will need to contact me on Tindie if you want to do that so I can give you payment instructions for the ADC.

Ok, thanks for the informations. I live in France, could you ship the boards here ? How much would it be for the shipment ? I hope it would not be too much a pain to send abroad. Best regards, Tristan Cousin.

[phil-barrett]

The shipping costs are shown on the tindie site. Shipping to France is a little less than $20 USD. No additional shipping cost for the ADC.

I ship internationally so it is very easy for me.

Hello again and Happy new year ! I have spent some times reading your manual and some of you blog posts to understand better the process of assembling your T41U5XBB, loading its Teensy with the apropriate firmware, and running it. The aim is to foresee some possible issues or incompatibility between your device on one side and my needs and situation. I guess you do not earn a lot from each sale compared to what I would have to pay, considering your expenses, shipping fees, TAV, etc. I will therefore try to be as short as possible in my questions and thank you warmly for whatever replies you may take the time to give me. These are the questions the answers of which I was not able to reply or understand fully through your documentation and my knowledge. My situtation is this one: I plan to use my CNC mainly for plasma cutting, with 3 cartesian axis and a 4th rotary axis. I currently still have some EMI issues remaining in spite of various shielding and grounding tasks. I expect especially your electronic design to relieve this problem. I guess therefore the ethernet version is better than the USB version, I think USB cable was the cause of most o y issues (And yes, I fully agree, EMI is so invisible and mysterious, it often looks like vaudoo, I used to call it shamanic until I read you) I have no Internet connection in my workshop, therfore no router yet. I just have one motor and driver for my Y axis, on which my X axis is in hangover. It may be sufficient for a plasma use, not for possible addons like a routing spindle. So I may later install a 2nd mirrored Y motor and hence need a 5th axis control, should I want to make X an Y square. My main questions are about the ehternet feature cable : - In the manual (page4) you say there may be two versions one with ethernet, another one with USB, which is not the case yet. I would like to be sure manual is up to date and the breakoutboard is ethernet compatible, even though it is called on Tindie a "t41*U*xbb". - It may look like a stupid question, but I wonder if the connection with the router or ethernet switch would work even whitout internet connection. - Also, I fear the the router or switch, or even the use of an extra ethernet cable between the router and the computer may be as well another exposure to IME and corrupt the connection. May be the TCP/IP protocol itself prevents from such risk ? I would be glad to have your feedback regarding the experiences you had or heard about regarding this configuration - I was considering as well to use a single and direct ethernet connection to my PC (pages 14 and 15), even though you say it may be more complex. But I just have one network interface connector in my PC. So I should in this case use an USB adpapter, which is pretty sensitive to EMI, I guess, no ? I have not understood if this aditionnal connector was just plugged for a temporary use, ie to set the IP address, gateway and mask, or whether it would have to remain and therefore pose a remainng EMI vulnerability risk. - I did not undertsand your advice page 14 "2. Secure a cross-over Ethernet cable. It may be unnecessary but it won't hurt." Does it mean we may rather need a straight cable and can not know it yet until trying ? does "secure" mean we may ned to have one axtra available ? - If the the Ethernet may not work properly due to EMI with T41U5XBB, do you think the Pico's wifi may be a relevant, noise-proof solution ? My last questions regard the THC plugin. I am just autodidact and in no way engineer in electronics and do not understand the I2C plugging. - How does it work ? I see on the THC board that tere are the same pins than those dedicated to I2C on the breakout board ( Halt, +V, St, Sd Sc, Ground). Is it enough, as for hardware connection achivement, to connect each end of 6 wires to the pin of the same name in each board ? (then I would recommend to add it to the manual, i may not be so obvious for other people too) - And what does ADC mean in this case ? Analog/Digital Converter? I thank you both for your work in general and for your replies. I am looking forward to finish my plasma CNC, and would be glad later if I can, to give some THC plugin feedbacks.

I'm running out sorry for the terse replies. I will be happy to elucidate further.

ADC = analog to digital
Any ethernet cable will work (crossover is not needed, I need to update the manual, sorry for the confusion)
There is only one board - naming convention happened before I decided to make one board work for both USB and Ethernet.
The plasma ADC plugs into the I2C connector on the board.
If you follow this guide, you won't need a router or switch - direct connect from PC to T41U5XBB ethernet port.

Looks like I’m going to get the ADC only for now. I wasn’t sure my board had the required connection to work, but I’ve since verified I have the i2C.  My shipping info is: Dana Smith 11190 Bonham Ranch Rd Dripping Springs, TX 78620. How and where would you like me to pay ? I think I’d like to buy 2 ADCs. With shippingThanks again!DanaSent from my iPhoneOn Oct 16, 2024, at 2:20 PM, phil-barrett ***@***.***> wrote: Yes, I just got a small run of the final version in.

Either put your email address here or connect to me via the Tindie page for the Teensy board. I don't want to put my email address on github and don't recommend others do that but it's your choice (wish they had a secure messaging option).
