Roy,

I found this, for your MonoPrice Printer

See if it explains things?

Mike

Michael, I'm a 3D printer noobie and literally just got a monoprice printer this week. I've tried to load your two knobs stl files that you shared into Cura to generate the necessary gcode. The first knob (tuning) comes into Cura as a speck with zero minutes of run time. The volume knob comes in with an error message saying that it was resized and it also has zero minutes of run time. I've downloaded a stl file from another source and it comes in correctly and shows what I guess is a normal runtime of 1 hour and 58 minutes.?

Your knobs where going to be my first attempt to print something because they seemed small and useful for one of my BITX radio! :-))

Any suggestions?

Thanks,

Roy

This is the volume knob with the small shaft hole.? You could drill it out for 6mm pots?

Have the same chip on mine. Worried about powering it up now.

Could have some RF capability.?? I know Florida DOT has fiber running in the Turnpike and Interstate rights-of-way.? The citizen call boxes are RF, but the cameras I see on top of the poles do not appear to have any RF.? According the company website they say they are IP based, but who knows.

In Cura one of the buttons on the left side when viewing the knob will be for scaling. It's been a while but as I recall there are tool tips for the buttons. It'll pop up a dialog which is self explanitory.

I have the Sotabeam cw DSP filter as a peripheral, using it on another rig, and it is good. ?I tried it on the uBitx and it is a definite improvement. ?However, I'm also going to try my old favorite, the Hi-Per-Mite SCAF from Four Square QRP Group (). I have one with for each of my rigs and love it. ?The excellent QCX transceiver uses it as well.

Those Knobs were designed for the FemptoBit 2000 GHz Radio!? Made for Flea Hams!

It is all in scaling, Cura may think the units are MM?.? In inches the tuning knob is 1.2".? The volume is 0.625".? So if you don't see those sizes your software is set up wrong.? Some programs automatically scale.? Others printed the knobs and had the same problem.? They fixed it in Cura with settings.? I use Simplify3D, so I can't help with Cura.? I am sure someone on this list uses Cura?

Hit YouTube also?

Keep going, I have 3? 3D printers and it is a Hit and Miss every print.??? Wait until you find yourself getting up in the middle of the night to check how your part is going!

Mike,

Once the Arduino IDE opens up and you can see all the code, make sure you have the Raduino plugged into a USB port and then go to the upper tab named 'Tools" and choose "Board" then select Arduino Nano. Next, goto "Tools" and select "Port", now select your USB port you have the Raduino plugged into. Now you are ready to see if the code will compile. Click the check mark in the upper left hand corner and wait until it finishes saying 'compiling sketch'. If everything is okay it will report 'Done compiling'. If you have made it this far you are ready to upload the new firmware to your Raduino. Now click the --> button at the top of the window and it should upload the Sketch into the Arduino. When it's done it will say 'Upload complete' and you are good to go. Let us know how you get on.

Hi Jim, May I ask what you chose to use in place of your Raduino boards??

Justin N2TOH?

Stephen:? Glad you scored a couple of the cases.?? Have not seen a better case for the uBitX or BitX40. One of the best things about the case is way it is constructed.

Pulled down all of the cases from the shelf at Skycraft and saw the different configurations. The case I bought had no heat sinking, so I doubt (at least with my case) had any RF capability.? Guess there might have been several different variations/pieces of the IP Video Surveillance System that used the same case. Only a guess....

Should work fine, as suggested in post 42723 a few days ago:
? ? If really paranoid, perhaps add an 8 or 9v linear regulator (or string of diodes) to reduce Vcc into the TDA2822M.

Though I'd now tend to go for 6v, especially if you have a WX part.
Just because you're paranoid doesn't mean they aren't out to get you.

Batch 3 .. First we have heard that there was another batch in production!

I will add your photo to the display of "damaged goods" on ubitx.net!

I have some TDA2822 replacements ordered and will try them, but the adapter with the LM386 is working well, though the adapter will fall out of the socket if the rig is vibrated much. ?If I decide to keep it that way, I may need to figure out a better adapter.

Howard K4LXY

How about stacking a few 1N4001s in series in the power rail to the?TDA2822 ? Not ideal but could provide a couple extra volts headroom and easier to install than a regulator.

Since Nick's PC board?(VK4PLN) ?isn't available yet, I solved the problem using an inexpensive filter from QRPme. ?I inserted it in line where Nick did. ?Now I can work on the next uBitx challenge.
