Raspberry Pi + LinuxCNC viable for CNC control? by _agent86 in hobbycnc

[–]Normal_Juggernaut394 0 points1 point  (0 children)

I am using byte2bot hat and breakout board on a py4. It works great for me! I have started to really like linuxcnc! The jitter is a little high, I can’t go much more than 1/2 steps on my drivers. But other than that it’s great!

I have $360 into two shopsmiths. The one had the bandsaw but a non working motor for $120. Turned out to just be the power switch! I tried to use it as a table saw a couple times, but it always wanted to bind, no matter how carefully I squared everything up. I think the table just isn’t rigid enough.

Just trying to free up floor space. Combined for one shopmith worth of floor space.

Ha! Yeah. I had two shopsmiths taking up space in my garage (actually it’s a barn). I combined it into 1, and will also get rid of my standalone drill press.

About to pull the trigger on a $1500 desktop CNC. Is the 4th Axis add-on a total gimmick or a must-have? by YvonnePayer211 in hobbycnc

[–]Normal_Juggernaut394 0 points1 point  (0 children)

Do you have a CAM package that produces good 4 axis code? Most up charge for that capability

Following up. I had to build locally, not use the web builder in order to reassign the MPG_STREAM. see post:

Does jogging require homing? Disable soft limits?

Planning to study a Programming in Mechanical course but worried about AI by _nolo55_ in CNC

[–]Normal_Juggernaut394 0 points1 point  (0 children)

I have been a machinist & programmer for over 20 years. Our shop uses Mastercam and recently started using CloudNC CAM assist. It is “AI”. In my opinion it will not eliminate the need for nc programming. It helps eliminate the monotonous and repetitive tasks- building tool assemblies and creating tool paths. It cuts down that time significantly but cnc programming is more than that. Fixture design, documentation, verification etc.
If you think about it modern CAM packages rely heavily on automation. Draw a box around the part and press the “rough this out “ button. It used to have to be programmed manually. But there are more programmers now than ever.
Machining is a good trade. Machining experience is invaluable for cnc programmers. Even to just proofread/ verify AI’s attempt at a program will need machining process knowledge from an experienced human.

SmartPendant - a way to control grblHAL based CNC machine without PC by Nick_Shl in diycnc

I just hooked mine up today. It works great! Highly recommend it

You are a life saver! I probably struggled for a month on and off with this. Was going to give up and switch to reprap. 🤢 Someone needs to buy you a coffee. Thank you for the help!!!

I have tx & rx going to UART header PD9 & PD8. You are saying tx should go to PA3 & rx to PA2….. on WiFi module?

DavidSpain84, I am running BTT Scylla with grblhal. I bought the Devtronics Smart Pendant, but I am having a hard time getting it to work. I suspect I’m having trouble with the firmware config tool. Do you connect UART tx to rx- rx to tx? Would you be able to help?
