As of 07/18/18 printrbot has ceased business operations.
Fortunately there are enough spare parts here to temper any concerns regarding this news.
Interest here in printing started late 2014 stimulated by publicity
regarding SeeMeCNC and MRRF which are both in the area.
Soon after witnessing printrbot evolve from wooden framed
printers to the Simple Metal, it was time to try......
All of the printers here thus far are fused filament deposition using PLA.
While resin printers have made substantial progress.
IMHO they still have fume too strong for use in the home
in addition to the ever present liquid state toxicity.
Dec 2014 A printrbot Simple Metal kit was acquired and immediately assembled.
Started by extruding 1.75 mm PLA filament thru a .40 mm tip on an ambient 150 X 150 stock bed.
From there progressed to a printrbot 150 X 150 heated bed (not shown) that ironically was never powered for heat.
It's heavier MIC 6 platform did however make for a more stable printing surface.
Dec 2016 After months of procrastination, a Matrix Precision 200 X 200 bed was installed....
Used for some time and then uninstalled as it just seemed to be more mass
than the printer optimally worked with at the speeds desired.
Jan 2017 Heat plate added to the Matrix bed upgrade on printrbot Simple Metal,
along with SSR for bed heat control and heavier Meanwell style power supply.
Buildtak and PEI then replaced the blue Painter's Tape.
April 2017 Switched to printrbot's 150 X 250 heated bed upgrade.
Winter 2017-18 Ordered one of the few remaining Simple Metal barebones frames
and scrounged the remainder of parts needed to assemble a second printer (shown on left).
Let me tell you about Buildtak which is currently on all the print beds.
It works really well for print adhesion...maybe even too well.
Have on occasion resorted to blue tape again on top of the Buildtak to facilitate easier print removal.
July 2018 Printed Z nut bracket thingiverse design
Replaced the original delrin nut on Simple Metal.
Installed the 8mm upgrade and the Z axis had greater ease of motion.
Also found my upgrade to have a good deal of backlash.
This upgrade is now back in the parts bin.
Both Simple Metals now have printed .250" lead screw stabilizers from design found on thingiverse
and are currently printing to satisfaction. Your results may vary......
Early 2018 Both Simple Metals also now have upgraded cooling and DIY LED illumination.
While both printers have heated bed, the external SSR control is gone.
Nov 2018 Both Simple Metals received Ubis 13s hotend upgrade
along with the suggested 2nd cooling fan.
Feb 2019 Printed a new style Ubis fan mount, matching part cooling fan shroud,
and those nifty Z probe nut thumbwheels. Looking at the color combination
one might wonder if I have a tinge of Prusa envy? Yea, kinda, maybe....
However, have yet to get drunk enough to spend the crazy kinda dime he's asking for his printers.
Dec 2019 Psst..come al little closer and I'll let you in on sumthang.
It's rumored a Creality Ender 5 appeared here before Christmas and it's awaiting attention.
If true I'll get right on that (yea right) and post pics soon maybe, possibly.
Today's Baby Steps...
Wire support for the winter project shown below.....
Winter 2019-20 Project
June 2019 Brook Drumm was moving and had Simple Pro basic frame 'kits' along with most likely
a plethora of other surplus printrbot inventory; ...anyway to make a short story too long.
In spite of previously purchasing/returning an assembled Simple Pro "back in the day" (height of production).
I went ahead and purchased this basic frame along with a Gearhead Extruder Assembly.
The finished product this time around will be sans the touchscreen, ribbon cable, & original board(s) as the "CLOUD"
printing has long been shut down and the G2 control on the Simple Pro left much to be desired IMHO.
This purchase made perfect sense at the time as the quality of other construction with use of linear rail was just too good to pass up.
A few items do require improvising.
The original two piece Y idler pulley was molded delrin with both halves trapped by bearings.
My first iteration is a split design printed from pla....material choice for ver.2 if necessary will depend on how long ver.1 lasts.
The F6 board seen adapted here is becoming more difficult to acquire,
so while not necessary, the SSR shown mounted on sidewall is precautionary.
Jan 2020 Found a 4 line display and adapter for the printrboard, printed up a Prusa style housing from thingiverse
then drew up and printed an adapter plate for the Simple Pro.
Late November 2019 Designed and laser cut bed sub-frame to enable better leveling and bed heater for the Putzbot Pro project now under way.
Dec 2019 Final iteration? Re-dimensioned cut file (300 X 165mm) to enable using 12" X 12" birch blanks.
Considered using the acrylic on hand, but with the house sealed for winter, that idea was short lived.
The sourced bed heater (red) can also be seen mounted.
Sometimes one gets lucky ...
The knurled bed adjusters just clear the motor plate and align to trip the X axis end stop, almost like it was meant to be.
Dec 10, 2019 The mechanicals are complete, now it's just a matter of wiring everything up,
which will probably take awhile as other distractions currently beckon.
March 19, 2020 Yet to be tested or calibrated...but it is all together.
April 14, 2020 Yup, it's still waiting to be powered up.
The Ender 5 purchased last year is now out of the box.
02/06/20 Discovered the PrinterMods X axis linear rail conversion ordered turned out to be an Y axis linear rail kit when shipped.
Guess I should have checked the package contents prior to starting.
220 X 220 X 250
One of the simplest assemblies encountered thus far.
Have modified the X axis with linear rail and updated the extruder to direct drive.
Probably should get it up and printing before adding any other mods.
It was pointed out to me there may not currently be enough table space in the lab for it.....hmmmmm.
This is for any doubters......More than enough room.
April 2020 With spring approaching and no hitch on the Hustler for a lawn roller, (probably for a good reason)
designed and printed this from the least suitable material, which is PLA cause that's all I have.
Attached with M5 socket head cap screws, cause again that's what was on hand.
Let's see what happens.
Speaking of spring, that is usually when 3D printing curtails around here due to better weather.
Uhhhh...figured I should finally get this Ender 5 "winter project" up and running....
It wasn't a perfect print...but read on to see how much effort I didn't put into prepping this printer.
Purchased 12/01/2019, converted to direct drive and X axis linear rail during assembly sometime in February 2020.
Powered up for first print April 2020; hey that's just the way I roll these days....
Did I mention have yet to even scroll thru the onboard menu.
All I really did was a casual physical bed level with copier paper about a month ago.
I frequent a good many 3d Forums and have noticed a recent trend seems to be
quieting stepper motor movement either thru dampers or improved board drivers.
Printing here is in an extra backroom and honestly to me a printer is
like a child out of sight in the house, it's when you can't hear what they're doing that you should be concerned.
I can often tell what stage a print is in elsewhere in the house just by the sound and find that somewhat reassuring.
