I need to upgrade the firmware on my RB1 and am looking at the wiki below. I'm not sure which I should go with and have one modification I think I need to take into account. I am using the stock controller board and have the LCD. I did upgrade to +Peter Stoneham's MK8 single mount kit and had upgraded to a 20 tooth pulleys. I also have the proximity sensor and am wondering us auto bed leveling was ever completed?

Hello everyone!

I haven't been on the community in a while. I have an original rigidbot big which I haven't used in a while.

I'm a bit of a wordy person so will try to be concise.

Part of the reason that I haven't used it is because I haven't been able to print reliably with it. I also have a much smaller "trinus 3d printer" which has been reliable and working like a champ. This past week a friend needed a large part so I fired up the Rigidbot big, but 2 hours into it, it failed. It looks like it literally just stopped. No reason. I was able to get it printed by splitting part into 4 pieces on the trinus, but I want to give some love to my rigidbot.

So my questions/asks are this.
1)what are the bare recommended upgrades recommend which will have minimum time involved, to fix rbb? Should I upgrade print head, motherboard, step motors? Combination of these?
2)OR at this point am I better off selling rbb v1 and getting a built rbb v2?

I want to add that though I am confident technically... I don't have alot of spare time with work, home, 8 year old, trying to start a business, etc.

One of my frustrations with rbb was that I would start a weekend project and design something, and when I would go to print it I would run into a bunch of problems printing on rbb and would wind up throwing in towel and giving up after a few attempts and tweaks on weekend, before returning a few weeks later when I was ready to "deal with it".

I must admit, the trinus has been a joy for me because I can get a print completed on first try, make adjustments and then print version 2 or 3 of whatever I'm doing. At least for the weekend whenever I go through some of these creative splurges... However the trinus only has less than 5x5x5 inches of build space (closer to 4.9) and can't meet most of my needs for slightly larger projects.

Any suggestions, recommendations or remarks welcome.

Overall, if I could put in a few dollars and time, would love to get my rbb up and running so that I can count on it.

Thanks in advance!

I work from home and my printer sits right next to me. This isn’t normally a problem but I designed a part for my Toyota Tacoma that a bunch of people want so my printer has been running a ton! We keep our house fairly cool so this made printing ABS a little tricky unless I ran a space heater in that room alone.

Anyways, I had cardboard taped to the frame to control drafts and try to maintain temps but that just looked terrible. Today I whipped up a partial enclosure that leaves a gap open for the Z to rise. I might completely enclose it some day but this is actually working great as is! Temps are holding very nicely!

so after a couple years, i dusted off the ol' Kickstarter Rigidbot.

apparently even after years of neglect, my bed's still level and my tape's still Good!

Today I finally installed the filement protector box I built in December but never had the time to install. I will put some silica gel inside.
It was built with a hat box from Amazon and some 3dprinted parts.

BACKGROUND: I have replaced my 24V 16A power supply with a new one 20A 24V. All things seem to go better but after hours of print, I experienced again the issue of the "ghost down button" and my flow moved from 100% to 98% (of course very little, and not 10% and button always pressed as in the past, but it happened). The button is detected by the motherboard when on one port there are around 4.3V. So I am convinced that the "Ghost down button" effect was always originated by a drop of the 5V power.
I have the original RigidBot board hacked with a square hole over the 5V regulator on the plastic box to get air, and an aluminium dissipater over it, plus the fan mounted under on the board box.


Today I was looking at the schematics to better understand, and I see that:

- The stepper motors are powered by 24V - direct power
- The Extruder fan is 24V - direct power
- The extruder is hotted by 24V - direct power
- The board logic is 5V, regulated only by an IC that take the 24V direct and convert to 5V. This 5V regulator does not have any "screw" to regulate the 5V.

So if I measured the 5V from the USB LCD Panel, and I got 4.98V.

- is this too low ?
- what can I do to bring at 5.0 / 5.1 and what influence the regulation of this voltage ?

Assuming my 24V is not 24 but 23.80 (I did not measure it yet)...

- has this an influence on the final 5V output since the difference 24/5 is so great and the regulator IC has no screws to regulate the 5V voltage and seems to do all automatically (perhaps wrong)
- My opinion is that there is nothing I can do, and if certain condition, hot, overtemp, overpower may cause the chip to fail the regulation of the 5V.

I was just able to recover a print that was 44 hours in and had a nozzle jam. I measured the print height, went into the G code of the print, and found what layer was at that height. I deleted everything previous to that layer and added a little bit of code before it:
G28 X Y (to home the X and Y Axis only)
G1 X0.0 Y0.0 Z140 (move two mm above the layer I wanted to start on)

I copied the first coordinate out of the layer I wanted to start on, and added two mm to the Z axis so it would move into place while staying above the print.

G1 X84.050 Y47.834 Z140

Then I left the rest of the code as-is. I set the nozzle and bed temperatures manually, and started the code I had modified. It did exactly what I wanted! I ran the first layer 5 degrees hotter and at 10% speed to try and remelt some of the previously left print. After the first layer, I turned on the part cooling fan, turned the nozzle back down 5 degrees, and ramped it back to 100% speed! Seems to be running like a champ! I’m glad I have that flexibility with this printer.

I think I may have burned out my motherboard. I was printing something today, print finished, then I swapped filament to do another. Now the printer is not turning on. I have the original IAP motherboard, but with the upgraded Reliabuild power supply. The power supply is getting power, but the printer is not turning on when I flip the switch. I tried the original power supply and same issue. Is there a fuse I may have tripped? Is my motherboard done?

Happy Valentines Day to my wife! I printed you some roses and a vase. Didn’t have time for the stems, but you get the idea.

Plastic Roses, Plastic Roses
They don’t wilt and they wont grow
But they manifest a beauty
That will never dim or slow

True, they may be imitation,
But they’ll last eternally
Like the everlasting constant
Of the love ‘tween you and me.
