Upgrade paths for Plus V1

Upgrade paths for Plus V1

Postby tgfisher » 2017-Apr-Mon-16-Apr

Hello, I've been out of the game for a while. I have a Printrbot V1 (the old laser cut one), and I was getting it back into operation.

Lots has changed since I last printed (~2014) I was wondering if it would be worth it to get a new extruder/hot end, or if it was possible to add autoleveling without too much hassle.
Currently it is the old stock printed gears, and 3mm filament extruder with a 0.5mm nozzle.

Any ideas would be helpful.
Thanks!

I found the E3D V5 to be a worthwhile upgrade. If you get the V6, you'll have to make an adapter because it's too short to work with the original extruder/hot end geometry.

I recommend bracing the Y table with aluminum angle irons to prevent it warping with heat, humidity, and pressure from the Y belt tension. There are posts about doing that.

I don't use and don't want an auto-leveling probe, but I did change the way the Z zero is sensed; that hidden screw with the jam nuts is nearly impossible to work with. You won't want to do what I did, but there are some other old threads about better Z adjustment (see Plexus, for example). It's really not that hard on a Plus to shim the bed so it's parallel to the X-Y plane, and once you have it, the geometry stays stable for months at a time - so there's no need for the auto-leveling probe. Also, doing this allows you to use glass on your bed, which is very flat.

I'm not sure if you can find injection-molded gears, or maybe metal gears; those old herringbone printed gears are pretty rough. Printrbot sold injection-molded gears for a short while and I got lucky enough to buy one set when they were available. You might ask them if they have any old unsold stock.

I'm perfectly happy with using 3mm filament. I have several nozzles, but the 0.4mm one is my workhorse.

My Rev D board died, and I'm on a Rev F4. At the moment, I'd say keep away from the Rev G board because it's not as well supported. Partisans say it can run faster and smoother, but the same can be said of a Jaguar versus a Toyota; did you ever hear the one about Jaguar owners needing two cars because one would always be in the shop?

Cable chain to reduce probability of fatigue failure in wires
E3D V5 Hot End, 0.4mm nozzle, also 0.8 and 0.25 in use occasionally
PB fan mount + 40mm fan -- using printed mount adapter, not the E3D supplied fan
Injection molded extruder gears
Optical Z "endstop" (custom designed and built)
Have used many pounds of T-Glase filament. Now also doing some work with Ninjaflex SemiFlex

My old herringbone gears are looking a bit more than rough. I'll check on the extruder, thanks for the head's up on the V6.
I'd kind of like to stay with the 3mm filament, since I have a couple kilos of it (though I'll have to see if it is any good any more). I have some extra nozzles if I can find them here...
Good point on the leveling probe. I do have glass, binder clips and kapton, so I should be square there. I did get the platform leveling upgrade back in the day, but I never installed it since I already had it shimmed. If I'm out of wack, I'll try to find/install that.
My 1st print today reminded me on the need for constant Z endstop adjustment... I'll look into posts on that.

Thanks for the ideas,
Cheers.

Drawcut's spur gears are still available on thingiverse. If you're not sure you can print a decent copy one of the printing services can do it for you.

Like RJ I snagged PB's molded gears and have been very happy with them

Got some gears on their way. Good to see some familiar usernames, Mooselake.
Cheers,
