Initial bench tests were very successful last night. I was finally able to get the 4408 mounted after getting my printer fixed up (Creality has a nice metal extruder replacement/upgrade for $10). I made a standoff platform and an adapter plate so I could use the small holes for mounting the board without tape. The adapter plate lets me use M1 screws to hold the board to the platform without crunching the components on the underside.
Sorry to poach this thread but after seeing the video with the nice slow start sequence I had to give this a try.
The motor control is ERR like but with full tuning access. I didn’t play with the tuning but did try the accel/decel settings. Tapping the throttle will give you a roll speed which is nice. I only ran it on my bench but found the speed control to be very smooth and responsive. The app actually shows the voltage supply readout. On my bench setup I have 16VAC on the track and the app showed around 20VDC and change max.
I got the chuff adjusted pretty close for now, with the setting somewhere around 68. This engine has an 18:1 gear ratio with a baby Pittman and ran pretty well with ERR. Wonder how it calculates chuff, maybe commutator pulses? I found settings for articulated and 3 cylinder chuff since I was wondering. Didn’t see anything for compound though. I will try the DDE stuff when I get it on the layout.
The sounds are a bit dry until you add reverb. I found a bit of reverb on chuff, whistle, etc., added some depth. Sounds are loud and clear and as you can see in the photos I am using a single Lionel Fat Boy that’s good for 1W but I may look for a similar speaker with higher output since the Blunami says it has can do 3W.
Next up is wire up and configure the lighting.
My Base 3 is in and I’ll probably get it later this week. I am thinking it may stay new in the box for a little while though!
