These are some nice looking machines! Great job.

Just thought that I would share a few tips for those who are planning to do a controller upgrade on their K40. These are general tips, not specific to any specific controller.

1. Plan out the upgrade - create a list of all the required parts, and break down the upgrade into simple and testable steps. This is the most important part of the upgrade process. Poor planning, or trying to do too much at once usually leads to errors and frustration.

2. Keep the wiring neat - color coded and neatly run wiring can make troubleshooting problems much easier - if it looks like a rats nest, it will be difficult to track down problems.

3. Document the upgrade as you go along. By doing this, you can undo changes much easier if necessary, especially when it comes to firmware or software issues, and will also make life easier if you decide to upgrade a second machine.

4. Take pictures and document the original configuration. That way you can always put it back to stock if necessary. Nothing worse than having one or two critical connections that you can not figure out.

5. Take your time, rushing will only increase the chance of error.

6. Use a static ground strap. The chance of destroying a component from static is a distinct possibility. It does not happen often, but it is a case of better safe than sorry, and ground straps are very inexpensive.

7. If you are unsure of how to do something, reach out to the group for help, there are some pretty smart people who are always willing to help.

8. Double check all connections before powering the machine on, especially the AC connections and the high voltage output to the tube. I recommend always using a GFCI outlet, and make sure all tools are out of the machine, and all components are secured to the case properly.

I hope these tips help, if you have any questions, please feel free to comment or contact me.

What is the best way to make a continuous loop out of GT2 belt?

What is the best program to edit the Smoothieware configuration file? It looks like crap in notepad.

Just got a notification that I have a parcel at my U.S. drop warehouse from Cape Electric Supply. Have no idea who they are or what they have sent. You never know, it might be something cool, but I'll have to wait a while before I can get there to pick it up and solve the mystery.

SO I did some math and figured out that it now takes 10,220 pills a year to keep me somewhat healthy. Now at 1 calorie per pill, I am getting an extra 5 days of food a year. I figure that's why I can't lose weight...lol!

Well it is about time I clean up my electronics fab room. It has gotten out of hand, can't find anything when I need it. Probablly going to take at least 4-6 hours to get it all organized again.

I have an SVG file that I seem to be having issues with. I am runniny Turnkey Tyrannys ramps 1.4 setup, and was hoping someone on here who is also running this could give the file a try so I can check my Gcode against yours for errors.
Thanks in advance

I am currently developing a glossary for one of the projects +Arthur Wolf is developing. It deals with configuring 3D printers/CNC machines/and Laser cutters. I would appreciate it if people could list terms that they feel would benefit by being in the glossary. I have got a good headstart on the project, but I know I am missing a lot of terms.

If anybody is in need of a stock K40 head, I have 2 available. One has the mirror and lens, the other only the mirror. I am asking $350 for the complete one, and $20 for the one without the lens. Neither unit has air assist, but I can provide 3D printed air assist nozzles at no extra charge. These came out of lasers that I upgraded. They had very little use.
