Currently thinking about a roughly half-length/width lowrider 4, still trying to get my head in order about the table.
Will open a thread with my own questions once I’m ready for that.
I’m planning on some carvings and making furniture on it.
If everything works out, might even build a new kitchen with it!
For sure a lowrider would be useful for a kitchen and more ambitious projects. I would recommend you to open a new thread so we can help you on what your needs are for your build/project
New to the forum. I built my second cnc during Christmas break last year, and it’s been a whole new learning experience.
Found this forum because i started with fluidial and loved it, but have now fried 2 integrated esp32 boards, both suspiciously proximal to dropping my pendant. So, rather than keep on replacing $50 m5s, i decided to try the cyd.
I soldered a new esp module and it’s back up and running, but the s3 in the m5 was also dead. Apparently i got flux or something in the sd slot, so now the push-push on the controller doesn’t work either.
While building it i noticed the sd slot and my search on whether it’s usable in place of the controller slot led me here.
I should mention i did not get a jackpot because i haven’t been able to find any in stock. The v2 sounds like a big improvement over my pibot 4.9, if nothing else for the esd protection.
I’ve added ferrite beads to everything going into the pibot, and added a couple 220ohm resistors to the tx and rx lines. I saw some mixed comments on tvs diodes and haven’t found any in the 3.6v range with low capacitance yet. I’m currently using gx-16 connectors at both ends with shielded cable, but will be swapping to the rj12 connector for the cyd.
Any other recommendations for hardening this princess?
looks like a great community. Wish i got the jackpot, but at least pibot also supports the fluidnc project. It’s a huge improvement over the old arduino grbl/ugs setup of my first diy machine.
First off, Cory, welcome to the V1 community forums.
OK, a bit of details from having and using M5Stack and CYD pendants. Never, ever, ever, connnect or disconnect the pendant when the machine is on. Even on a machine with otherwise reasonable ESD protection, you can blow the ESP-32 on either side by doing so.
Unfortunately, that includes disconnecting things even intermittently during a drop.
Particularly if your machine doesn’t have suitable ESD and current inrush protections, you’re risking killing the microcontrollers during plug/unplug events.
You are welcome here whether or not you have a V1 machine or V1 controller.
Jackpot continues to be in development, and the Jackpot V2 board will be short lived, the Jackpot V3 is almost ready for release and it’s a refinement of the good things Ryan started working on with the V2. The original Jackpot will stay as it has removable ESP-32 and removable TMC2209s, which fits a specific niche.
Ferrite beads won’t do a damned thing for ESD protection. They don’t do much for serial signal cleanup, either.
Really, the ideal would have the system use a proper connector that connects the returns first as you connect it (for ESD protection, not for enabling powered connecting).
Also, something you should consider is static issues related to dust collection. This is a major source of blown controllers and pendants in the desktop CNC world.
FluidNC and Grblhal32 are indeed major improvements.
I figured as much, but a friend who does industrial controls suggested that stepper noise might be causing some issues, and i figured it couldn’t hurt.
I’ve gathered that from my troubleshooting research, i guess i’ve been spoiled by modern pcs and higher end systems. I never realized the esp was so sensitive.
I added circuit breakers, but that’s about it. I assume i should be doing more grounding of components? Maybe a tiny fuse on the controller power supply? Any other suggestions?
I’m tinkering out of my depth, but diving head first because my employer is pushing me into a position as an industrial automation engineer from my previous manufacturing engineering technology position, so i’d rather ruin a few esps than an allen bradley.
OK, Sorry to be so slow with this, life has very much gotten in the way of my projects.
Printed one of these, that case is a beaut. I will need to get better pictures of the RJ12 connector breakout, I still don’t think I have the right one.
Ryan- on the printables site for that case, there’s a question from a maker who couldn’t find the right part. On one of these threads I mentioned it was a bad link, and you were going to update that posting.
I can’t find the forum thread here nor see any updates over on Printables about that.
I like this enclosure way better than the one with the three physical buttons (which are redundant with the UI on the CYD having touch buttons).
Most likely I’m going to swap my two CYDs that are built up over to this when I confirm the RJ12 breakout that it needs.
I’ll post a make over on Printables as well when I get one fully assembled.
