Re: Rambo Board Electrical issue

I received the new RAMBO board from JJ. Got the relay recommended above. Got a heatsink on Amazon for 5 bucks. Rewired everything over the weekend and am back up and running. Thanks again everyone...I truly appreciate all the help and advice. I think we can mark this thread as "solved".

Re: Rambo Board Electrical issue

#1 SeeMeCNC is awesome...they got back to my ticket and authorized and RMA even though I didn't ask for it.

#2 You guys/gals are awesome...I appreciate all the advice.

#3 The SSR idea is great...going to order the one recommended above while the RMA is underway....thanks again!

Re: Rambo Board Electrical issue

Thanks...I opened a ticket with SeeMeCNC...it seems to me that if there have been at least 3 nearly identical failures (mine plus the two others noted above), there is a design defect. Any recommendations for the SSR? This solution seems to make sense to me.

Re: Unable to print in PLA

I had almost exactly the same issue and received the following advice: "Make sure you know what brand your stepper motors are. This happened to me and it actually says the fix for it in the manual. Kysan AND Automation Technology stepper motors need to have a small tweak in the firmware. I don'...

Rambo Board Electrical issue

First, some Context. I have been printing heavily on my Rostock Max V2 since I finished assembling about 4 weeks ago. When I say heavily, I mean about 20 hours a day on average. Since the original build the bed has taken what seems to be a long time to heat (10-20 minutes), but I really don't know h...

Re: Fried RAMBO??? Thankfully not...

Thanks everyone for the ideas...fuses arrived today and I will re-assemble the printer in the next day or so. I'll try the leather and brass brush ideas and will be sure the nozzle is tight. And...thanks for brightening a frustrating situation with a bit of humor (loved the VW belt change video).

Re: Fried RAMBO??? Thankfully not...

So, anyway...while I still have all my fingers...and since I have little interest in purchasing cleaning towels with or without boogers...can anyone suggest a method to keep the nozzle clean(er) when using PLA? The issue I have is that some of my print jobs are many hours long and often finish (or f...

Re: Fried RAMBO??? Thankfully not...

Below is an image of the nozzle which was the root cause of the issue. I printed about half kilo of PLA to get to this point. Unfortunately I was printing some very tall / thin structures (vertical axis windmill blades) which failed a number of times. The extruded PLA adhered to the nozzle and surro...

Re: Fried RAMBO

Thanks, Windshadow...I should have ordered from SeeMeCNC. BTW...here's an Idea for SeeMeCNC...after I started using my printer heavily, I ordered a bunch of "spare" parts (a few of everything I figured would wear out eventually). Naturally one of the things I didn't order was fuses. It wou...

Fried RAMBO??? Thankfully not...

OK....I'm stupid. I was trying to remove a nozzle from the hot end (it was covered with PLA so I had it actively heating). Somehow the wrench i was using arced with the hot end wiring -- the rambo board died immediately. No LEDs light. I check the 15 amp fuse and that actually looks OK. I see there ...

Extruder Motor Hot

I've really just begun printing (less than 2 days on the machine) and am now trying PLA. A couple of times the filament has "jammed" necessitating some minor dis-assembly to free the filament. The extruder stepper motor is VERY hot. I believe it is partially melting the PLA in the EZ-strud...

Cracks in ABS

Hi Everyone, Now that my machine is done, I have started doing some awesome 3D printing. However, I am having a recurring issue that I don't understand how to fix. I am printing with ABS filament at 228C, bed is at 80C. Anything over a few mm has small cracks between some layers. See an example here...

for my own JPGs I have to be sure to only use images less than 720 pixels wide to avoid it I thought it was a quirk of the Apple Macintosh Safari browser.

Off to a great start. SeeMeCNC got the machine delivered a day early (unfortunately I was out of town). Box arrived in pristine condition. I haven't had a chance to inventory yet, but here is the unboxing! BTW...I could use some guidance on posting images from imgur. If I use the [IMG] forum option,...

Re: 3D printed rocket contest at MRRF!

Has anyone here ever called the FAA about a rocket launch before? Are they open and receptive about it, excited that you're an aerospace enthusiast even, or is it a difficult process that they generally don't want to be a part of? For general model rocketry launches an FAA waiver is not required. T...
