Welcome to the SeeMeCNC Community

I've had pretty good luck (a couple dozen decent prints - haven't been running my printer much lately) running with a Smoothie hooked up to a BBB that's running Octoprint. I was using a Raspberry Pi to run Octo for a while, but the USB/ethernet shared bus made for painfully slow uploads at times, an...

I've been running Octo on a Debian BBB rev C for a few months now after I kept running into random problems with my RasPi. Works fine, and it feels like it's an order of magnitude faster on file uploads (the RasPi USB is a bottleneck), calculating print times, etc. You can use the angstrom-based ins...

Those are the standard FSRs everyone is using. They're not really compatible with heated beds.

I didn't bother too much with ensuring it's square, if it's off 1 degree you can compensate that anyway when you calibrate it :] Trust me - it's much easier to build it square than to try and calibrate out the non-squareness. I believe Repetier-Firmware can handle rotation of a tower, but it might ...

I noticed something is finally listed as in stock.

My understanding is that all other things being equal, changing arm lengths tends to affect cartesian X/Y (part scaling) more than Z.

Thanks for the info! It may be fun to try the 6 different filaments (if I can afford them) :) I've got orders in for the Tritan and PCTPE - 2 lbs of each (tritan is $30/1lb spool, PCTPE was $22.50/1lb). That was special pricing (I think) for backers of the Kickstarter campaign, even though it didn'...

His message appears to be spam but if you go to the site, there is an option to join up to print parts that they need printed. With this option forum members can possibly make a few bucks, if it is true. That's not the point. Even if it's true, they're advertising via forum spam. While it's more to...

Gaps on perimeters: Your extrusion width parameter might be too big. My 0.4 nozzle usually gets set between 0.41-0.44mm, depending on the specific filament and how fast I'm printing. The wavy patterns - is there any play in your hot end mount? If you push the tip of the hot end, is there any play in...

This is what I'm doing over on my Smoothieboard. The board itself including the steppers actually do off 24V. I have a stepdown converter for the hotend and fans. A single 100W-rated converter is more than enough.

I like the idea of having the probe detach from the end effector while not in use, but having an integrated sensor is cool too. Here are a few of the methods for probing I'm aware of; 1) Limit switch contact with bed 2) Electrical conduction with bed 3) Magnetic proximity to bed 4) Pressure contact...

I usually just print straight from my desktop, but lately I have been wanting to do other heavy CPU stuff on it while printing so I started using the LCD and SD card more so that I don't screw up a 10+ hour print job. The only problem with the SD card is that it takes forever to upload through Repe...

626Pilot, since you're running simulations and not actually moving the machine - would it make sense to run the simulation on the host and then use the machine to make periodic validation runs? Your host calibration routine could change any of the needed parameters on the EEPROM and go from there. ...

You're hitting on something that I think is the next big thing in home CNC... Closed loop positioning. It's starting with ZProbes, but eventually I think we'll have it on all movement. Could switch to servo motors instead of steppers. I've been pushing this idea for some time now. There seems to be...

Well, here's a crazy idea: Let's just probe the bed ONCE, and then use brute-force computation to simulate EVERY possible miscalibration within some reasonable range. For each possible combination of endstop offsets, delta radius, tower angles, tower radii, and arm lengths in a given range - and th...

I'm still working on heuristic calibration stuff for Smoothie. Latest rev is here: https://github.com/626Pilot/Smoothieware" onclick="window.open(this.href);return false; That code is, of course, highly experimental and useless unless 1) you have a Smoothieboard or Azteeg X5 and 2) you're...

Would some one minde sharing gcode of 3riple or double extrusion? It's not a gcode thing - your slicer (and the parts you feed into it) need to be set up. All you do in the gcode is tell it to do a tool change. The slicer should do that. Most common thing today is to use the 2nd extruder for suppor...

So, what is indicated is that, one should change the fans because they will be receiving the input voltage on the rail. What about the motors? As they are current controlled will their PWM values need to be changed aswell? Also, for the fans can i change them in the firmware? Or must I change them?...

You would need an extension board to do this. Fortunately, since the Kraken predates the Tri, one of our fellow users already figured out how to get 4 extruders, even: http://forum.seemecnc.com/viewtopic.php?f=55&t=4522" onclick="window.open(this.href);return false; Over on the Smoothi...

Looking at the code in the Temperaturecontrol module in Smoothie, it looks like it would be easy enough to add the code in - just need an if statement to force the integral term to zero outside the desired control band. I just need to download the toolchain so I can build my own firmware, I guess. ...

They also need to include integral wind-up prevention, which would prevent overshoot at startup. Right now the integral error term can drive you to max_pwm. AHHH that's the term I've always been trying to figure out! The integral accumulates the temperature difference even when it is passing the ta...

I think you don't have anything patentable here. The application of tungsten disulphide as a coating? I just don't buy it. Nor do I see the need for you to pursue a patent. I'm personally very off-put from supporting your good ideas when right off the bat, you're seeking to patent them... So much f...

Keep in mind that all of these improvements are transferable to other hotend designs as well. I think the Tri hotend is the best value and highest performing one, but I'll try to get these jam-free components into after market production for other hotends. I still gotta figure out how the patent wi...
