Should be ok but you need to ensure that the two power supply cases do NOT touch each other in case the cases are tied to ground (the two grounds are not at the same potential)by dart16 - Safety & Best Practices

Quotedjlapan So I tested my output to the heat bed. I am getting 9.96 Volts and the resistance is around 1.8 to 2 ohms. I've double checked to make sure that I have wired the heat bed correctly through the wiki, which I have wired correctly. Both power leads coming into the RAMPS 1.4 are reading 12.01` Volts and 11.97 Volts. I did tin the wire ends that are coming from the head bed to the RAMby dart16 - Printing

I have two z steppers paralleled up onto one stepper driver, I tried moving the second stepper motor onto the spare (5th) stepper driver and un-comment the #define Z_DUAL_STEPPER_DRIVERS line in Configuration_adv.h, however I couldn't get it to work. To be fair I didn't pursue it because I have not had any issues running both z stepper motors from the one stepper driver, I just went back to paraby dart16 - General

I think Tray is thinking of PC power supplies, not the server power supplies. The server power supplies do not require a load to stabilise the output, they are rock steady, unlike many PC switch mode PSU's that are built to a price. The cooling fan can also be made to operate according to the internal temperature of the PSU by external jumper selection if required. you can also wire two in seriesby dart16 - Reprappers
The OP's question was about reasons for buying a more expensive board and, IMHO for all the obfuscation, there is still precious little anyone has put forward to justify the price tag. For £20 you can buy a miracle of modern(ish) electronics that can perform magical feats at the press of the print button, for £100 you can buy a controller with some bells and whistles - if bells and whistles areby dart16 - Reprappers
Does the z carriage move correctly when commanded manually? What controller software are you using? You need to decide if the Z carriage is moving because it was commanded to move, in which case the problem is with your slicer. If it moved without the command to do so you have a controller hardware problem.by dart16 - Reprappers
Quotedc42 I have seen many tens of posts on these forums by users with exactly this issue. The 800mA rating of the regulator is ok but it's the power dissipation that is the problem. I ran some tests and I found that the regulator temperature is OK even with 15V input if you don't have an LCD connected. Once you connect a graphical LCD, the regulator overheated even with 12V input. YMMV, it depeby dart16 - Reprappers
There is not much there that warrants an 8 fold increase in price in my book. Voltage regulator on the arduino is not a problem if you are connected to either a powered hub or a computer as +5v also comes down the USB cable. (if there even is a problem - -AMS1117 is rated at 800mA) Pot twiddling is just as much fun as software tweaking. you can use 24v on an Arduino/RAMPS board 10amps through thby dart16 - Reprappers
The G29 command is just the probing command, you need to send the M280 command to extend the probe, then G29 and then the M280 command again to retract the probe.

This usually happens when the movable contacts in the switch make poor connection with the fixed contacts, arcing occurs and welds the contacts together, a sharp tap normally frees them off but that is not at all acceptable. The ratings given are, of course, Chinese Amps and Volts which, just like the Chinese mAh ratings for batteries and lumens output for LED torches are wildly over-optimisticby dart16 - Safety & Best Practices
Not likely to be the RAMPS at fault as it just takes the separate control signals from the arduino and sends them to the correct stepper via the pcb tracks.. IMO much more likely you have toasted the arduino when you fried the stepper boards......by dart16 - Printing

You say you have tried multiple external MOSFETS and a relay...?? Perhaps you should draw a diagram of exactly how you have wired your RAMPS board to the heated bed? Perhaps the original 'faulty' MOSFET wasn't the only fault with the RAMPS board? Have you stuck a meter on the MOSFET gate to see if the CPU is doing anything?by dart16 - Reprappers

What software are you using to connect to and control your printer? You can see what the ambient temperature being reported by your thermistors is as soon as you connect in pronterface. that will tell you if the maxtemp being triggered is due to an incorrect config setting or a dodgy thermistor Once you can verify the thermisor is giving sensible readings send a M999 to reset the overtemp and watby dart16 - Developers
Unbolt the extruder motor from the x carriage and turn your entire extruder motor, extruder, heatsink and fan through 90 degrees and re-bolt it to your x carriage to reduce the torque you are applying to your x carriage bearings.

Do you have a fan blowing on the stepper drivers? These can run hot, especially if you have not setup the current your motors require correctly. If they get too hot they are supposed to stop supplying current (stopping the stepper motors) until they have cooled downby dart16 - General Mendel Topics
You need to ascertain if the problem is lack of heating for the extruder or over cooling by the 'fan' Which 'fan' are you talking about?.. the extruder cooling fan or the filament cooling fan? The extruder cooling fan should just blow on the hotend cooling fins and not on the heater block itself. . I would disable the filament fan all together to see if the situation improves (you don't need theby dart16 - General Mendel Topics

Sounds to me like your thermistor is working fine - it reports the ambient temperature and it reports the increasing temperature as the hot end heats up... what appears to not be working is the regulation of the power going to the hotend heater.
