An odd thing started happening on my second extruder.  I had to shut it down suddenly and ever since, the temp on the second reads too high.  At idle, it shows 70 when the other extruder and bed read 20.  It seems to warm up when I turn it on, but it won't really go any lower.  I swapped cables and even switched 1 and 2, but it doesn't change so it seems like something in the board or firmware.  I reflashed the board, but that didn't change it either.  Anyone have any ideas.?

What is the correct syntax for the configuration of nozzle offsets?  I can't get the printer profile screen to finish saving--it just sits there.  I was able to set extruders=2 in config.yaml, but I can't get the offset to show up in the interface so the gcode viewer doesn't show them lined up.  It isn't a big issue, but I wouldn't mind getting it working right.

I finally got around to rewiring my bot so I can use both extruders.  I'll call this first one pretty good for a first try.  The alignment appears to be right on, but I need to look at what it is doing between switches because it jammed each time it switched.  I checked the orange before one switch and it was free to move until just before it started extruding and it did something that stuck it pretty good.  Besides that, I haven't been able to set the nozzle offset in OctoPrint so it is isn't displaying g-code right and it now seems to think extruder 2 is the default for single color prints and prints off to the right side rather than in the middle.

I haven't had time to dig into this one yet as it was the last thing I did last night, but this is what happened when I finally rewired my bot with the board with Peter's mount.  The trace on the board smoked almost immediately followed by line 6 on the ribbon melting down.  The cable was plugged in securely at the time and I just set it in for the picture.  Hopefully I will have some time tonight to take the meter after it.

+Peter Stoneham Shots of my setup.  The right side is not yet wired up, but I recently added a piece of filament to try increasing the tension on the left.  You can see the shim poking out from behind the bearing.  I just realized that my gears might have a bit different shape to them as yours.  The groove with the teeth is about as wide as the bearing and the current community picture makes it look like yours have narrower grooves, but I could be wrong.

I have also had trouble with the filament jamming and grinding away at the filament, but I am pretty sure I have that fixed now.  I even had one heat break so plugged up that I had to use a small drill bit to carefully convince the plastic back out.

1st version of my garage door monitor using one of my Spark (now +Particle) Cores.  These wifi enabled arduinos can be programmed and monitored over the internet.  I attached two magnets on the belt and two hall effect sensors detect if the door is open or closed.  I have a relay on board to control the opener from my phone, but it isn't wired in yet and only triggers the blue LED at the moment.  Once a couple more parts arrive, I will move the circuit over to a protoboard.  For now, it notifies me every 15 minutes if the door is left open and logs any activity to Drive.

Wanna design quality #pcb #boards without spending much penny....Here are some suggestions

Post has shared content
Thought I would share my espresso setup with all of you. I wanted a cheap setup with the results of that more expensive equipment offers.

I put links in below to all my tools and the mods i did.

Espresso Machine:

For $89 you really cant go wrong. This is a single boiler with brass fittings and 15 bars of pressure. The only catch is the steam wand is a panarillo and the basket is pressurized. But as you can see from my pictures i have replaced the steam wand with a traditional and the basket with a non pressurized basket as well as made the bottom naked.

Steam wand:

If you look it up on amazon its going for 44 bucks plus shipping. The cheapest i found was from seattle coffee gear. Make sure its the version 1


A grinder is THE most important part of good espresso, a blade grinder wont do. This one is the ONLY entry level burr grinder that you can get for espresso. Its $129 but its well worth the investment especially since its the only one that can do espresso under $300.

The after market basket

This is the only place i found to carry this basket. It also is the ONLY one that fits and is non pressurized. Trust me when i tell you this is the basket you want. For 10 bucks. Well worth it, the results over even the standard unpressurized mod is significant.



Knock box

Tamper Mat


Milk Frothing Pitcher

DeLongi Double walled espresso shot glasses

Scale for dosing properly:

Airscape container:

sources for modding:


Steam wand replacement walk through:

It really wasnt that hard to do. I now have coffee as good as you can get from any high end coffee house. My espresso has notes that i never knew espresso could have. The potential in this little 89 dollar machine is enormous and when using the same coffee from my local fine coffee house I achieve similar tasting results.

If you need any help or advice, im always here. Ask away in the comment section
