Welcome to the SeeMeCNC Community

I fixed the issue by reflashing the firmware. When I have more time I will revisit the autocalibration on octopi

Okay, I thought I was following Geneb's instructions carefully but I have done something wrong. Now when I run a G29 command it crashes the hotend into the bed. It starts out normally but instead of moving parallel to the bed to the X tower it slowly crashes into the bed and drags itself towards it ...

Hello all,
I just installed Octopi on my V2 with the HE280. I need to run the auto calibration. I used to plug the printer into my laptop and run it through mattercontrol by pushing the auto calibration macro. Im not sure how to make that work through Octopi. Thanks in advance.

Sorry to hear about that. What kind of trouble are you having? The community here are very kind and helpful so dont be afraid to post.

Welcome aboard. You will find a wealth of knowledge in this forum. Please don not be afraid to ask questions and share your experiences.

ABS slurry is ABS dissolved into acetone. It acts as a base layer painted onto your base plate to help with adhesion (and curling) of your first layer..

I second your post Tim. It was an outstanding event. My hat's off to all of the great people who organized and participated.

mhackney, I would love to buy you a cup of coffee and and ask you about a million questions a MRRF

Welcome aboard. I live in the south suburbs. It's nice to see I'm not the only one in the Chicago area with a MAX. Perhaps we could get together and compare notes. I would also recommend attending MRRF. The experience is not to be missed.

Thank you for bringing this up viciousXP . I also upgraded to the HE280 and have been having hit or miss results with my prints.

Get well soon. You are a wealth of information on the site along with so many others. I have learned so much thanks to this forum.

Mchackney, I'm guessing that you are insinuating I am making a mountain out of a molehill and your probably correct.

briankb, I have the tricklaser one. It's a perfect fit for the Max

So if my bowden tube was 600 mm long i'm guessing I would create a macro that is something like; M302 S0 (cold extrusion min temp 0) G1 E600 (linear move extrude 600 mm) M302 S170 (cold extrusion min temp 170) Ok so if I add M81 (turn off ATX power supply) to the end G code commands it should turn ...

I know the amount of electricity the light ring uses is infinitesimal small, but I was just curious if there was a line of code or something that would do that.

Howdy all, I asked this question on an older thread for the MAX3 board and have not received a response. I will repost it here and hopefully someone else can benefit from it besides myself. I know you can power a light ring off the HE280 board. Is there any way to turn it on and off? Thanks in ...

Howdy all, I guess this is a 2 part question. The easy one is what G code would you use to have the filament feed itself down the bowden tube once the extruder motor engages with it. The second question is how do you learn how to write the macro for this sort of thing? Web sites, books, or other ...

Is there a way to switch the light ring on and off if you wire it to the HE280 board?

I have a v2 that I just (two weeks ago) installed the HE280 hotend on. I bought the v2 in November of 2015. I'm pretty sure it has the newer power supply. Much of what your saying is a little over my head in terms of understanding. I am confident in my mechanical skills but the software side of life ...

Should I do a PID aoutotune for the HE280 hotend? I have been doing pretty well with it "out of the box" until i printed with a temp of 225. It would only go up to about 218 until I turned up the temp a few degrees and it rose a few degrees. it seems to be consistently 5 degrees low.

I bought this one and it has done well for me.

The part casting is an interesting idea. As far as the anthills go, I thought you were referring to something like this. http://www.anthillart.com/

Xenocrates, what parts need to be polished to a mirror finish? (that is well within my capabilities) I was thinking I would just pull parts off the J head clone and get a bigger nozzle (or drill out an old one).
Pardon my ignorance but what are the advantages of casting parts?

I have a drill press, taps and dies, bandsaw, all kinds of toys. And the block was free and I have a virtually inexustable supply of the blocks.

I have this solid aluminum block roughly 1" X 3/4" X 3/4". I was thinking either a dual extruder or pseudo volcano. Input or other suggestions? I included a picture next to a J head clone for reference.
