Re: Heaters killing Rambo while heating up to temp

It doesn't have a THING about "someone afraid to do it right". Do you honestly think letting a vastly inexperienced builder near a power supply where they've got to hard wire the mains plug to it in order to use it? That's begging for a lawsuit because Joe Derp burned his house down or el...

Re: Nathan's Rostock build

My LCD controller does not know when a card is put in it. It simply won't detect the card. Not surprising. It must have gotten quite a shock the last time. This sounds like another part to send back to SeeMeCNC. At least the base system seems to work. Did you try going through the menus in the LCD ...

Re: Extruder Test

The red lever is just a spring loaded bearing that pushes the filament against the hobbed gear. It doesnt activate the motor. You have to get the motor turning in software or through the LCD controller in order to feed filament through the extruder motor.

Re: Making an aluminum base and top, Need Your Feedback

I think you could fit all the electronics in a base since you have to allow for the height of the stepper motors. I think you could easily have an external 12v power supply and have everything else self contained. That way external wiring would only be a single pair of wires instead of a huge wiring...

Re: new extruder that works

Steps per mm will depend on your extruder's drive ratio, hobbed roller size, your stepper motor's degrees/step, and your micro step size.

Or you could just guess, then measure the filament it moved, then adjust.

Re: What's the Best Belt Tension?

Calculating belt tension from stepper holding torque like you're doing doesn't seem right. Belt tension in our case is acting on both sides of the pulley so they effectively cancel each other out. The tension isn't the load on the steppers. The cumulative mass of the carriages, arms, effector, and h...

Re: Cause of "The Lean"

When I was trying to solve the layer shifting issue, i tried motor current settings from 100 to 255. With higher currents thenmotor drivers will run hotter but you seem to have adequate cooling there.

I'd look again at the noise issue. Do you have the shielding on the cables connected to ground?

Re: Heaters killing Rambo while heating up to temp

Is the power supply cutting out, or are you sure it's the RAMBO that's shutting down?

Sounds like it may be a power supply issue; sounds like it's cutting out due to the load.
I never liked using hacked up ATX power supplies when a dedicated 12v power supply is so cheaply available (ebay, amazon).

Re: Cause of "The Lean"

I had a similar problem. My fix was to reroute my extruder stepper motor wiring far far away from the endstop wiring. Somehow it was triggering the endstops and causing a shift in my prints.

overkill for rambo? No, the rambo board draws hardly anything at all. overkill for your printer? Who knows, it depends on what heated bed you have, hot end, stepper motors, etc...

Basically, you are simply defining the distance from the end switches to the "bottom". You define the distance in firmware, and fine tune the screw so the real life distance matches. When you build the machine, nothing will be perfect, so the adjustable screw is there to fine tune the towe...

Re: My "FUNstock MAX" has arrived!

I use silicon tape also, but after a month or so, its a good idea to slice it off and reapply because it does get hard and crusty with the many heat cycles the hot end goes through. At least my tape did. I got mine from amazon under the F4 brand name.
