Re: Heated bed on Mega2560 & RAMPS 1.4 showing 358° C? - 5 years ago

Thanks for the suggestions. Beside the wires melting, there were no sign of any damage on both the board/headed bed. How would I test to see if it is the ADC pins that failed? Do I do a continuity test to ground on those 16 pins?

Heated bed on Mega2560 & RAMPS 1.4 showing 358° C? - 5 years ago

So I have this printer for awhile now (from Kickstarter) and one of the component just quit and I don't know where to start to diagnosis the problem. It's a Rigidbot Big that is running a board based on Arduino Mega2560 & RAMPS 1.4. Not sure what the problem is (short circuit?) but Cura is reading a very high number whether the heated bed wires are plugged in or not at 358° degrees C. - I ha

Re: RAMPS 1.3 and Heat Bed Connection? - 12 years ago

Had some time to test some more and giving this PSU a third attempt to power the whole system and is working somewhat. The max temp it can do before failing is 30C to the heatbed. I attached the 5A to the yellow 24pin cable. I can set 185C to hotend and 30C MAX to heatbed in my test. Not sure if that is the optimal temperature for PLA and if running this for entire print at peak is dangerous. Any

Re: RAMPS 1.3 and Heat Bed Connection? - 12 years ago

Just a update that it appear that something fail during the spark as I can not get a constant flow to power both the hotend and heatbed from the same PSU. I tried PCI-E to heatbed and sata/8pin to hotend so it does not look possible. Would just die as soon as I try. The weird thing is that it work once..when I power the heatbed first then the rest but...I can not recreate the same result again..

Re: RAMPS 1.3 and Heat Bed Connection? - 12 years ago

I had it hook up to some 6 pin connector and everything went well but when I try to measure the 5A power slot it cause some sparks and as soon as that happen the whole system shut down (Ramps and PSU). I couldn't power it on afterward and had to reset it by pulling out the green/blk pin. I tried moving and powering the 5A side by connecting the 6 pin cable and it didn't change anything. Still cou

Re: RAMPS 1.3 and Heat Bed Connection? - 12 years ago

Ok so it look like the problem was in fact the PSU. I replaced it with a brand name one with max amperage of 28A and the unit is working fine so far beside a small mishap that invole spark when I tried measuring. There is no problem trying to power my heatbed and hotend seperately but the PSU would give and die out if I tried powering both so that earlier spark did a number on something and the o

Re: RAMPS 1.3 and Heat Bed Connection? - 12 years ago

Hi, this is what happen when I used a load such as a small bulb. Connected it to a red/black wire and the system stayed on until I manually power it off (5-10sec). I turn it back on to test it again and the system and bulb power on for a sec then shuts off. Only time it would turn on again for over a sec is when I relocate to a different red/blk wire and the process repeat it self. Pretty bizarre

Thanks for all the information but I can't get it working for some reason. I connected 2 Yellow / 2 Black to 11A and 1 yellow/black to 5A all 22 AWG and have a wire connected from GREEN to BLACK. When I turn it on it just power the system for a second then it power off. Tried connecting pin 1 to pin 11 but that didn't help. I checked Green connection multiple times and tried connecting to another

Re: RAMPS 1.3 and Heat Bed Connection? - 12 years ago

I was a bit worry that 18A yellow plug would be too much amperage for the 5A positive slot without some resistor in place. I will be connecting my mother board pin14 green to pin16 blk like you mention. As for the heat bed I am going to use some excess nema 17 motor wire (1.4mm thick) to connect to the D8 slot of my ramps and use the same wire to extend to and from the PSU if it is too short. Not

RAMPS 1.3 and Heat Bed Connection? - 12 years ago

Hi, so I have a heat bed coming soon and I want to nail down a couple of things first so I don't fry myself or the electronic. I want to replace the old setup(single 12V 5A PS) with a PC power supply that has 18A to power the whole thing including the new heat bed(Max 11A). Do I just use these 2 yellow pc plug and have them go to 5A+ and 11A+ plug and the black one to negative?

Re: PLA keep on curling up on exit on extruder head - 12 years ago

Hi Mark, any update on when you would be comfortable recommending an alternative hotend for all Sumpod user? Haven't seen any update on your blog and my current heat resistor lead broke off during a print a few weeks ago and this seem like the perfect time to retire the hotend. Looking to order something this week in case they need some lead time and have something arrive here to work on before t

Re: PLA keep on curling up on exit on extruder head - 12 years ago

Just manage to push out a finished calibration block below. Not bad for having to continuously assist the stepper motor for almost 1 and a half hour. Beside a sore thumb, I am pleased with the end result. Found out that it is often a hit and miss with this system and require a lot of supervision so I am looking forward to your recommendation ASAP. Just curious as to which two kit are you looking

Re: PLA keep on curling up on exit on extruder head - 13 years ago

1. extrude manually lots - ie. 100-200mm or so - mine too will curl up but then after a couple of 10, 20 even 30mm extrudes will run ok (i have 3mm PLA). at 205. (need to make sure you can do this well to start with i think). Going back to basic is a good place to start so here is the manual extrude (1.75mm PLA) 2. then when i start printing i will get the first layer down ok (and fill) a

Re: PLA keep on curling up on exit on extruder head - 13 years ago

Roger, I find that it stick better on paper than the blue masking tape. I am not sure why my print is jumping xx mm every few layer or so. What ever is causing that is in this gcode I uploaded if it is software related. It would normally extrude great for the first layer then it will struggle to fill in the gap and goes downhill from there. I had some time to trouble shoot this some more and I

Re: PLA keep on curling up on exit on extruder head - 13 years ago

I have been trying to figure this problem for some time now and really need some help with this. The machine mechanically runs ok but the extruder doesn't sync with the speed and has problem extruding the correct amount. After the first layer, it just leave a small dot of plastic only on top of the layer underneath it and does not connect or fill in 40% like I set in Splicer. I read some where th

Re: PLA keep on curling up on exit on extruder head - 13 years ago

Thanks for the input. Can some one tell me why ReplicatorG would retract my fillament about 3 inches before a print and is there a way to stop my PLA from keep oozing out before and after a print job?

PLA keep on curling up on exit on extruder head - 13 years ago

I am having a hard time trying to get my PLA to extrude evenly down as oppose to go against gravity and curl up as soon as it leave the printer head. If I use some left over plastic on the end it would be enough weight to pull and guide the strand down but without that the PLA would just curl up and form a mess at the exit. I am using some extra yellow 1.75mm PLA that came with my order from Ulti

Re: Setting Up New Printer Dimensions? - 13 years ago

I guess it was homing correctly in Printrun before a print but quite the opposite when using ReplicatorG. In ReplicatorG it would skip the homing and goes right to printing but it doesn't seem to print what I loaded. It move maybe 10x as much as it should but I double checked with a digital caliper and even tried scaling the object down. I have also check for belt slippage and grip and it is all

Re: Setting Up New Printer Dimensions? - 13 years ago

Hey Tom, I think I got the connection correct as when I use Printrun the initial stage move all the axis toward the limit switch and stop but not sure why it doesn't do anything after the print head is ready. The software limit switch is set in my Configuration.h file for all three axis "const int X_MAX_LENGTH = 120;" I am using this and as you can see that it is a very tiny pully so it shouldn'

I have this new printer setup and calibrated for some time now and what is stopping me from actually doing a full print run is that it would do the following in this two program.

Re: Stepper Motor making weird sound and acting funny - 13 years ago

cool, that seem to do the trick. another problem that I encounter now with the Z stepper motor. It doesn't like going up. When I tell it to go up it just spazzed out and doesn't move an inch. I figure it was too much weight and didn't have enough torque or something but when I lift the platform exposing just the motor it still doesn't want to move up. The weird thing is that if I press down 4x10m
