I recently purchased a package fo some cheap Arduino Nano development boards from Amazon. For a couple bucks more you get 5 instead of 3. The only downside is they have the CH340G serial chipset. In order to get these to program on the mac and avoid the stk500_getsync() errors a couple steps need to be followed:
- First download the latest serial driver for OSX from the vendors website here: Mac CH341 Serial Driver
- Follow the installation instructions in the readme.
- I had an old driver installed so I removed it first before installing the new driver and rebooting my machine
- Connect the serial cable and open the Arduino IDE
- In the IDE make sure you have the Arduino Nano selected and the appropriate com port
- This step is critical in the Tools menu select the Atmega328P (Old Bootloader) option.
- If you don’t to this you will still get stk500_getsync errors.
Hope this is helpful for someone having these issues.
I recently upgraded my build surface from Kapton tape on Aluminium to BuildTak. I was a little concerned about this because like everything else there are rumors that ABS won’t come off. But I figured for the price for 3 sheets for my little Thing-O-Matic it was worth a shot so I didn’t have to deal with blue painters tape if I wanted to switch to PLA. I found my BuildTak on Amazon for around $8.00 (3 sheets). I peeled off my old Kapton tape and cleaned off the print bed. I will say this is way easier to install than Kapton since it’s a small area and the tape forms nice bubbles under it when it adheres to the platform. I used the edge of a credit card to ensure good adhesion to the platform.
There are several reasons I will not use a Next Thing Co. C.H.I.P in another project.
