you need to create a new board definition to match you hardware. You can't not use a ramp and expect to be able to use the ramps or any other board definition, unless you put all the steppers, endstops, etc on the same pins.by Dust - Controllers
Ramps is just a break out board that puts the standard parts on known IO pins If you not usings a RAMPS, you will have to create you own board definition and assign all the required pins to the actula pins you have the cparts onnected to. Eg use marlin add your wireing to pins.hby Dust - Controllers
that’s the tricky bit... you either have to trace out the cct board or be provided with the pin definitions from the supplier It may be compatible with something that already exists, but there is no way to know till you trace it out.by Dust - Reprappers
re orentation, except that most software has the 0,0,0 point as defined. so if you make it somewhere else, the software controlls will be backwawards or out 90 degrees.. why make life more complicated than it has to be? And where you want it is also not correct. you must have the X and Y correct in relation to each other or your parts come out backwards!by Dust - RAMPS Electronics

looks custom looks like a one board ramps type solution. Check the main chip for a 2560 or a 1284p type number... If it is one of those it should be possable to get a standard marlin onto it, BUT and this is a large but, you will need to work out what pins are connected to what part of the board.by Dust - Reprappers
The pcb is also quite flexable and will bend down if you put any weight on the center, like a printed part.by Dust - Reprappers
You have to enable eeprom setting in firmware when you compile it first ie uncomment and recompile and upload to your board.by Dust - General
Use the m119 command to the printer to display the endstop status. then manual trigger (with a finger) and re test with m119 to verify they are are are getting triggered as far as the firmware is concerned. Looking at the picture I see several 'issues' min endstops are always at left, back and botom of travel. If its not at those locations its not a min endstop eg I can clearly see the X enby Dust - RAMPS Electronics
gcode requests a feed rate, firmware looks at requested feed rate, if its under max feed rate it does as its told, if its over it clips the feed rate to the max feedrate valueby Dust - Firmware - mainstream and related support
did you move your z endstop onto the zmax endstop connector?by Dust - Developers

there is no way to connect a solenoid to a ramps without extra electronics. Its just a arduino see to see how to connect a 5v io line to a 12v high current solenoid. Then you still have to control it... A m42 command on the IO pin will work. but how your going to generate gcode with that in it will require coding.by Dust - RAMPS Electronics
Yours is definitely a 16mhz crystal take a look at gen 7 arduino support Their boot loader is same cpu, with a crystal From gen 7 boards.txt file Gen7-1284P-16.bootloader.low_fuses=0xF7 Gen7-1284P-16.bootloader.high_fuses=0xDC Gen7-1284P-16.bootloader.extended_fuses=0xFC But most likely your board already has fuses and bootloader installed.

a standard cartridge will get really hot really fast even with pid being wrong. (unless P value is really low) I suspect you have may have a 24 volt cartage. running a 12v system, it wont get very far. Failing that you may have a damaged mosfet to your hotend. Check the voltage getting to your heater, check the resistance of your cartridge. If you getting 12v the mosfet is probably okby Dust - Reprappers
Most of it is interrupt driven... so difficult to trace threw. basically read threw the source files, and ask specific questionsby Dust - Firmware - mainstream and related support
It depends on how its wired... Some fans are just wired into power, so are always on Some are connected to a CPU IO line via a MOSFET, these can be controlled by software If its the latter sending "M106 S0" to the printer should stop it and "M106 S255" should turn it on full speed Some firmware also has "M107" to turn the fan offby Dust - General

Looks like their own board. Not to dissimilar to the all in one reprap boards that are out their. Apart from the buzzer which most board don't have. Connectors look better than whats on most boards.by Dust - Controllers
In reality most repraps are old fashioned serial devices It is just serial over usb for a the standard usb cable bluetooth is just serial over blue tooth You control it just like normal just over blue tooth. You can upload to sd and print over blue tooth, but will be slow to upload as your using real serial baud rates. Same issue when uploading over serial over usb.

If your short the +5 to gnd pins via mechanical endstops, this will kill the regulator nearly every time.. this is what the supplier is referring to... Putting in a pololu in backwards will also do serious harm... Power in backwards shouldn’t do that, but will probaby kill D2 Since you have no pictures of how you wired it... its all speculation.by Dust - RAMPS Electronics

Thats just over heating... that layer is to small. you need to a) add fans, b) add delays in your slicer if layer takes less than a certain time. or c) print two copyies of the part as it doubles the layer time.by Dust - New Zealand RepRap User Group

The reset is controlled by the serial DTR line, if this line goes low the board resets. Im guessing they are attempting to ensure this line stays high some how.by Dust - General
You seem to be confused on a few issues... Ill presume you really are talking about servos here, as used as bed probes "2) I had read that I should jumper VCC and 5V together or does RAMPS do this internally for me?" yes you do, no its a mechanical jumper, see the red in this picture, there should be jumper pins here and a jumper to bridge the pins. This livens up the 5v rail for the servo plby Dust - RAMPS Electronics
