micro swiss full metal hot end

Added one off these to my Finder. Seems to have fixed a few problems I was having.

Not bad

So, I did a print of the wheel hub. It turned out I tight fit. Too tight to insert the motor without having to sand the inner surface of the collar that will hug the outrunner.

I snuck back into the model to shave a tad off for the next print. The collar will help fit the wheel square onto the outrunner to prevent wobbling.

Balancing Act

So, I have printed the carcass of a 3d printed balancing robot.

I bought two gimbal motors.

I have my pesky gimbal controller from my lidar experiments.

Go figure, you can buy rock crawler tires for my old Venom Creeper for $5 a pair, so I opted for an indoor/outdoor self balancing robot. To fit the crawler tires I grabbed a 3D model of a beaded 2.2″ rim. I then modified it with freeCAD to fit over the gimbal motor – including a collar to fit around the outboard spindle.

I will mate the gimbal controller with a Sipeed Dock M1W to give the balancing robot autonomous smarts. Especially with the wifi link, it can still lean on more smarts off-board.

Groan!

All sorts of problems with Flashforge Finder and the USB connection. More often the software cannot connect to the printer.

I have swapped USB ports onto my PC, instead of USB hub, that doesn’t fix it.

Of note, when watching the devices list, the list flashes whenever I insert or remove the USB connecter from the PC, but oddly no change in the number of items occurs in the devices list. That seems to mean the PC is detecting the insertion and removal of the USB connector but the driver is not picking up the printer at the other end.

The printer is too far away to try other cables (I only have 1x3m cable). So, I am trawling for my Arduino MEGA (which has the same USB Type B connector. If the Arduino IDE has problems with the MEGA then maybe I didn’t buy as high a quality cable as I thought I did.

The only other way I might be able to get around this is to open the side of the cabinet, send the files by wifi, close the cabinet. Downside of that is I lose the control via the software on the PC.

Nuisance? Sure is!

Just doing a test print of 1300 to 1 planetary gears.

Toasty!

So, I have the incubator ceramic fan heater, or is it a ceramic incubator fan heater? The thermostat turned up. DOH! They didn’t send the one I ordered. However, the specs of the one that was sent is fine for the job. Jipped me 10c though.

Fuming!

Not really, it isn’t a fuming cupboard mwahahahahaha!

In fact, the unit sent is better, it has the temperature you set the thermostat at and the actual temperature reading provided by the thermistor.

Also wik, no wiring diagram for the item provided.

Depending upon who you believe the part is either YLN0709 or W1209WK.

In any event, here is the associated info you need. The unit I got is a 12VDC model. I got that as the fan heater is also a 12VDC.

I will be using the first wiring example above.
