Re: Trick Trucks - Lightweight Aluminum Carriages by Trick L

That is way cool! How do you attach those carriages to the belt?

BTW anyone on Firefox can right-click and "View Image" if the pics are cut off like mine were.

Re: Rostock MAX purchase poll

My first criteria was $/volume, but a very close second was "how reliable and easy to fix is it?" My thoughts were basically: - I haven't seen anyone who owns a MAX be less than enthusiastic - It's a kit so if I built it myself then I understand every nut and bolt in the thing for if/when ...

Re: Rostock Max V2 Shutting Down on Heatup

this may sound strange, but try something for me... put your ear up next to the machine by the power supply.... turn on your bed heat... do you hear the power supply make a small scream sound? recently I had the same thing happen on a machine I built and found a defective power supply that made a b...

Re: Hotend not reaching temperature

Did your thermistor come loose? Sounds like if it used to work until you cleared your jam, you might've nudged it out of intimate contact with the extruder.

Re: Extruder having trouble reaching 230c

Nope, at this point I'm just trusting the thermistor. I decided to order a thermocouple meter off amazon today (thanks for the idea), as well as some power supply extension cables so that I can install some regular molex plugs into the machine, making easier to swap out power supplies in the future.

Re: Extruder having trouble reaching 230c

I rerouted some hotend wiring, checked for accidental heat sinks, made sure the thermistor was seated well, and adjusted my fans' airflow. The problem is improved somewhat: the printer seems to be able to maintain a temperature of 220 now. I haven't wrapped the hotend in kapton tape as teoman sugges...

Re: Extruder having trouble reaching 230c

I repositioned my layer fan so that the airflow wouldn't bounce back toward the thermistor, rerouted some wires, and recalibrated the PID settings. I'm hoping that was sufficient; I'll report back here when I have some results!

Check out this nice overhang!

So I'm printing a large soap tray for the corner of our shower and since the legs are so tall, I wanted to give it some reinforcement if it accidentally fell over or we dropped it. My CAD skills are still pretty raw so some simple cross braces were the best I could come up with. I wasn't sure how we...

Re: Extruder having trouble reaching 230c

Actually yes, it's PLA! I know 230 is pretty dang hot for PLA, but I did some temperature testing and with the filament I have, 230 produces the best prints. Printing at the 190 range produced parts that easily broke apart by hand, 210 range produced parts that were difficult to break by hand, and a...

Re: Adding non-structural elements to the Max.

This may or may not be insightful to you, but if you installed the layer fan the way the manual says to, then keep in mind that one side of your hotend sticks out farther than the others. One (and just one) of my binder clips is liable to get pushed away from the platform because of the positioning ...

Re: Extruder having trouble reaching 230c

I have checked the thermistor and while I haven't tried to pull it out, I have nudged it a few times and it seeeeems to still be seated firmly. I'll have to check out my wiring like bot suggests for any unintended heat sinks. Thanks for that idea! I still have 10 hours left on my current print so I'...

Re: Extruder having trouble reaching 230c

So in the middle of a print tonight I saw the same issue - temp set to 230, actual was hovering around 208. So I took the opportunity to measure RAMBo voltages again - extruder output was bouncing between 11.1v and 11.3v, and RAMBo input was bouncing around 11.2v and 11.5v. I was actually surprised;...

Re: Extruder having trouble reaching 230c

Thanks for the idea, but it is 4.4 ohms - measured both at the extruder and at the RAMBo output (was thinking that maybe my crappy crimping was to blame, but it would seem not... this time)

Re: Extruder having trouble reaching 230c

Ok, I did some testing with a multimeter and I think I might be fighting with an underpowered power supply... but I'm not sure. Are these readings normal? There is some drop, but it's just on the edge of what I would call significant. Measured at RAMBO input: Printer on but idle: 11.8v Extruder heat...

I'm glad to hear you solved it! I gotta say that soldering the fan to the RAMBo was the most frustrating part of the build. I thought my eBay soldering iron and radio shack solder would be sufficient... nope. Instantly created a solder bridge between the two terminals. Luckily I was able to break it...

Re: Extruder having trouble reaching 230c

A few more details: the temperature graphs in Repetier-Host are showing a steady output of 100% so I don't think it's a PID issue - seems like the controller knows it's supposed to be hotter and is doing its best to make it happen. Here's a screenshot of what I'm talking about in the middle of a pri...

Extruder having trouble reaching 230c

So I've owned my MAX v2 for about 2 weeks now and things have been going pretty swimmingly so far, printing PLA at 190 no problem. However after some filament temperature testing I cranked up the extruder to 230c and I noticed that it presents a challenge to the machine to get that hot. I would susp...
