Welcome to the SeeMeCNC Community

Arrrgggg.... Just had the same bed heater connector meltdown. I haven't had my Max V2 opened up since I installed an HE280 upgrade in September. Lots of printing since then with no issues. Suddenly today a few minutes into a print theres an ugly burnt electronics and plastics smell. I went over to ...

I have a V2 but I did the HE280 upgrade. I think the PTFE tubing in the second picture may the one used to insulate the thermistor wires used in "Step 26 — Prepare the Thermistor." The PTFE tubing that you are looking for is the long piece of PTFE used for the bowden tube. Should be around 36" or m ...

I picked up a couple of these: https://www.tindie.com/products/freto/pi-camera-hdmi-cable-extension/ a few months back and I've been very happy with them. Allows me to use off the shelf HDMI cables to extend the distance I can mount my Pi camera away from the Pi and gets rid of the annoying ribbon ...

Looks like it may be hard coded further down in the js: self.beginDeltaCal = function () { numPoints = 10; // these should be configurable at some point. numFactors = 7; self.statusDebug(""); self.statusCalResult(""); If you change the numFactors to 6 in your local copy of the deltaautocal.js that ...

Just a comment that the auto calibration plugin was 7 factor when I installed it just after it was released. My diagonal rod length is getting set to 294.370 after my last calibration run with .03 deviation. I have a V2 with the HE280 upgrade. So should we be doing 6 or 7 factor? I guess 6 now that ...

I haven't tried it yet but installation of the plugin via the OctoPrint Plugin Manager also seemed to work. Use the Git master branch download URL (https://github.com/geneb/OctoPrint-Delt ... master.zip) in the plugin manager.

I actually run quite a bit of stuff on my OctoPrint Pi including pigpiod. I have mine set up with OctoPrint pluggins that leverage pigpiod to control some relays so I can turn my printer and some lighting on and off remotely. It also auto-powers off the printer 10 mins after a print completes. I've ...

Just a note that you can install the Arduino development environment on the Raspberry Pi and use it to upload new firmware to your printer. You will also need something like VNC installed so you can remotely access the Pi's desktop and the Arduino development environment. I always make sure I have ...

True. But then I'd have to figure out how it works.

It would be nice if Ryan added something to G30 similar to what @kraegar did here: http://forum.seemecnc.com/viewtopic.php?f=35&t=10757&hilit=G30 to allow probes at specific locations. Then if someone could convince @DC42 to add an API to his online least squares calibration tool we could create a ...

There is no control for the Part LED on the HE280. Based on the schematics in GitHub looks like the + side connects to the main +12V feed and and the - side connects to ground through a 470 ohm resistor.

Interesting idea. Firstly, there won't be any twisting under normal printing conditions, there is really no force on the joints and the springs are designed to eliminate backlash (a great feature of these ball & cup joints). I admit I'm a software engineer and its a long...long time since I took ...

Okay, here's a question/thought related to the new HE280 and some of the issues with the head twisting during the taping. The new head mounts the ball joints on the top of the effector plate while the old one mounted the ball joints on the bottom. I'm wondering if this allows the tip of the hot end ...

The video clearly shows the HE 280 twisting as it taps. That may be causing inconsistent results and thus the calibration errors. You could try changing the values below to cause the probe to tap closer in to the center (just move it in a little). Maybe it will cause the twisting to stop. <-EPR:3 ...

(1)<-Free RAM: 879 <-Autoretract:0 <-X:0.00 etc <-SpeedyMultiply etc <-iis2dh accelerometer intializing... <-start <<repeats from (1)>> I've seen this on my printer when the 8 pin HE280 connector was not seated properly and fully connected. Check your connections. I used my multimeter to do ...

There are full V1/V2 upgrade instruction here: http://seemecnc.dozuki.com/Guide/Rostock+Max+v1-v2+HE280+Hotend+Upgrade/49#s402 No wiring diagram but there is a detailed description of what wires to splice to the new whip as well as how to re-wire connections on the RAMBO board. There's also this ...

If its related to back pressure and a possible blockage have you checked to see how well the PTFE tube is seated inside the hot end. In the HE280 the PTFE tube is pushed all the way down against the heat break. Also make sure the PTFE tube is cut cleanly at 90 degrees. If there is any gap then heat ...

OK, Thanks. I was confused by the new auto level function that is added to the LCD menu with the firmware upgrade. It sets the bed temp to 65 and the HE temp to 200 before running. I guess this is not part of the SeeMeCNC mods to repetier for the accelerator upgrade. Although the HE heating ...

Just finished doing the HE280 upgrade to my V2. Auto calibration seems to work fine as long as the hot end is off. As soon as I set the hot end to be heated then the auto calibration fails at random points in the middle of the calibration sequence leaving the printer frozen. I've tried using the ...

Assembly instructions are now linked off the main site: http://seemecnc.dozuki.com/Guide/Step+1 ... ssembly/45

Waiting for my HE280 kit too....

Still looking for a layer fan design that works with the tricklaser LED ring. I haven't printed the stock fan, is it possible to put a standoff under it to use that design? I don't have the tricklaser LED ring but I did install a 60mm angel-eye LED ring and created the layer fan in this link: http ...

Thanks Eaglezsoar, teoman, Holy1. @teoman, Yes the tablet bracket is probably not enclosure friendly but the mounting bracket could probably be integrated into the enclosure bracket if needed. I haven't posted the tablet bracket files since they're probably very specific to the noname tablet I ...

Actually it looks like spring is coming early this year to Ottawa, Canada. We're supposed to be one of the top 10 coldest capital cities (formerly number 2) but I think most of the Northeast US had a harder winter than we did. I picked up my Rostock Max V2 from the Black Friday sale in November and ...

I'm in the middle of my build and I noticed the comments on the R4 bearings and bearing sleeves for the new idler bearings. I used a washer slipped onto a 1/4" bolt. I sat the bolt head on my bench pointed up and slipped the washer onto the bolt. After snapping a bearing sleeve on a bearing with my ...
