The only other thing I can suggest is that you get a fresh copy of marlin, only make the changes listed above and see what happens.by lazzymonk - General
pause pin would not be the problem. The fact that m600 is triggering at all means pause pin is defined correctly. the best way to resolve it would be to do something like this bool pauseAdded=false; void pause() { #if pauseAdded == false enquecommand("M600"); pauseAdded = true; #endif } then at the end of the m600 code pauseAdded=false;by lazzymonk - General
maybe the buffer size has been changed recently. you could try adding enquecommand("G4 P0"); more times and see what happens.by lazzymonk - General
if you look at my earlier code you will see that enquecommand("G4 P0"); is there 3 times after the m600 call. this is to fill the command buffer stopping m600 being added more.by lazzymonk - General
I print abs at 120, I find abs sticks much better and releases much easier when cool too. However I use 15v to get it there, which takes about 10 mins. I find it hard to keep a stable 110 with 12v.by lazzymonk - Reprappers
I've seen this done on large commercial machines (can't remember which). I really like the idea but the fact that it has been done means their is likely a patent on the whole idea.by lazzymonk - Developers
You can do it, but might not get any more power. If you connect another motor in parallel you would need to increase the current. But you can max out an A4988 with one motor. Connect them in series you wouldnt need to increase the current but would reduce the speed. Why would you need more power anyway? Is your y axis too heavy? or binding?by lazzymonk - Reprappers
Its all about resistance. A mk2a has a resistance of 1.0 - 1.2 ohms. 2 beds in series have a resistance of 2 ohms ( worst case ). 2 beds in parallel have a resistance of 0.5 ohms. You can use ohms law to calculate the wattage or you can use something like this the best bet would be a 24v psu and run them in series. 290w at 24v is 12amps. But 290w at 12v is 24amps. Thats a lot of current, wouldby lazzymonk - General
With a 300w psu, neither. Assuming it is a 12v psu. In series you would have a total of about 75w, no where near enough to reach usable temperatures. In parallel you would have 290w, far more than you want to be drawing from a 300w psu, even if it was only running the heated bed. You add your other electronics too and bye bye psuby lazzymonk - General
also check the voltage both at the bed and at the psu. You would be supprised how much difference there can be running at 11.5v rather than 12vby lazzymonk - General
Yeah that looks right. Do you have the servo connected? if so unplug it and try. if its not working with the servo unplugged then it must be a short somewhere on the servo 5v pins.by lazzymonk - RAMPS Electronics
I just want to verify you have it right. You would be surprised how often people think they have it right but dont. You can check there is 5v there, thats about it really. You could also check that nothing is shorting the servo 5v pins to the servo grounds.by lazzymonk - RAMPS Electronics
Can you post a picture? It should work fine if you are doing it correctly. I soldered mine together on the under side of my board.by lazzymonk - RAMPS Electronics
Personally. I would go with a RAMPS. They are very well documented, easy to use and modular so if you break one bit, just replace it. Also RAMPS are available from many places, I think the RUMBA is currently only available from reprapdiscount. Im sure other people with have something different to say, but thats my opinion.by lazzymonk - Controllers
You would need to move the end stop, i forgot about that. but still, software wise nothing needs to change with the endstop. I get what you are trying to find out ( i think ) What you have to remember is that it is all relative. the firmware and slicing program dont need to know if it is the x axis moving up or the z axis moving down. It only wants the nozzle to be the asked for distance from thby lazzymonk - Reprappers
@ cdru i do it with every print and i have been using the same plate for over a year now. nice find bobc ive used them before but never noticed they did them. I might get one soon and compare to the cheap plate i currently use ( its a bit banged up from trying to remove overly stuck prints, but still flat).by lazzymonk - General
Nothing else needs changing at all. Gcode and slicing software do not need any changes.by lazzymonk - Reprappers
try copying the file to the sd card again. It might have been corrupted.by lazzymonk - Reprappers
Makes almost no difference at all. The motor just needs to spin the other way. That can be achieved by either inverting the axis in the firmware config or simply rotating the motor connector 180 degrees.by lazzymonk - Reprappers
I use cheap and flat enough for me. Aluminium is better than glass i think because you can run it under a tap straight from printing without it breaking.by lazzymonk - General
cdru your following me around lol. Another alternative is something like thisby lazzymonk - General
you dont need anything fancy. Just a mosfet and an arduino. thermistors can connect directly to an arduino and the mosfet can too. but a few resistors are always good.by lazzymonk - General
personally i dont like all on one solutions. One silly mistake and the entire board is junk. I would recommend something with plug in drivers like a ramps. I like the look of the rumba board but havent got one yet.by lazzymonk - Controllers
They will be fine. the 5th and 6th wires are just centre taps. They can be left unconnected but insulated. You wont loose any torque. from the wiki Quote "pair" wires on 6 wire motors On six-wire motors you'll find two groups of three wires in which all three wires are electrically connected to each other. These wires are connected to the same coil, one in the center of the coil, two at theiby lazzymonk - Controllers
Just do a text search on the firmware for what you want to replace. Might take a bit of searching but should be difficult.by lazzymonk - Reprappers
I think ikea must sell more of those to reprap users than people that need a mirror. They are very popular and work.by lazzymonk - General
have you tried plugging it into the heated bed thermistor pin to see what it says?by lazzymonk - Reprappers
I would say do it if you can. It cant hurt and better safe than laying on the floor thinking I should have earthed that.by lazzymonk - Reprappers
No not at all. USB and even the on board regulator can supply more than enough current to run them without any problems.by lazzymonk - Reprappers
what type of extruder are you using? I had similar problems and it turns out it was the result of a slightly not round big gear on my gregs type extruder mixed with slight over extrusion.by lazzymonk - Reprappers
