Ramps 1.4 with LCD and SD support (Page 1 of 4)

lets start at the beginning with no controller or SD card support.
you need to load the firmware.

you can do this before or after you connect everything up.

Alright I did take a look at the firmware this morning. I don't mean to sound completely lost, but when you say load the firmware do you want me to make changes such as to motherboard 33 and other changes/ pin configure? I am assuming so but do not want to make any other changes to it till I understand the process.

Ok, that's the issue that I have been having, is that I am not sure exactly what to change. I know the motherboard is 33 but when it comes to the mm/s movement, pids, etc I am actually lost. I tried to use the formulas I found online but the numbers I come up with are completely different than the original press firmware settings. I have copied the original press settings over to the firmware I was editing and it moves the x and y but not the extruder or z. Then the endstops were also giving issues but I think I figured them out. Sorry, I am not that familiar with the proper way to set up mechanical in the firmware. I guess the main issue I am having is building the proper firmware. Maybe you could point me in the correct direction to understand the firmware settings?
Does the Marlin firmware you had me download have the correct pin configuration for the ramps, or do I need to change that stuff also?

Wow, I will be amazed if that's it. I have been changing things left and right because that's what the multiple sites that I have been to say is necessary. My board is 8x8 which I believe I will configure when I do the end stops and homing 203/200/0? I am using autolevel. So let me ask this. If I have firmware that is preconfigured for my press with E3Dv6 hotend temp configs. Can I just change to board 33, and add LCD and SD support and configure them? That would be super simple compared to using the ramps preconfigured firmware that I seem to have to change?
Again, I am very grateful for your help.

The biggest thing is getting the endstop logic and switches correct.

"just change the 2 in SD2 to 3 that'll set the dimensions."
I did do that but some settings are different for the sd3 that my sd5, I have different steppers and a different mechanical layout. Its as if when they made the press SD5 they change up some mechanical features. Or maybe that wont matter as long as endstops are configured correctly so it knows the size?

Just seen your next post, yes its just a modified version of the stock SD marlin firmware. So here is what I will do. I will  mess around trying your version and see what I come up with. What is the SD patch that is referenced in the config_h
I wont get to try it for about 1.5 hours as I have to head out. I will let you know where I am setting at that point.

Hi Wardjr,
I have to admit I am lost at this point. I feel like I understand everything you are say, but I just don't know what to do. I have edited the firmware that you mentioned to use. Change to Board 33 and change my dimensions to 203,200,0 to match my printer. If I load it I do not know how to test anything except by hooking up RH and using the command prompt. This did not work either as even though it said connected it wont accept any commands. I took the firmware and installed the LCD in it. Load it and the lcd works, I can move my x and y axis 1 direction, but my extruder and z axis do not move. I can hook those 2 motors to the x and y and move them but again only in one direction. Once they have moved that 1 direction they cant move again unless I shut it down and restart it. I apologize for my questions and fails, but I am at a total loss. I could post my sketch and have you look at it but not sure if that would do anything as you do not have my printer in front of you. How can I tell what version of marlin I am using so I can see if the E3Dv6 modified marlin firmware I have is older?

on the board you are connecting to S and -

max = 200 for x and y roughly

min = 0 for z
so when you home x and y go to 200 rear right of the printer
Z goes to zero which is home to the nozzle or end stop.

you want to connect to S and - as the black box indicates.  The X and Y get plugged into the set that is labeled X max and Y max then z goes into the one labeled Z MIN

you can ignore the plug in the the picture

What do you mean the picture isn't showing up?  I don't see how that's possible

So when you say Z will go to the nozzle or end stop I am alittle confused as my Nozzle has a mechanical switch on the extruder for bed leveling but my end stop is at the bottom of my printer. So in respects to that 0 would be my actual endstop and 200 would be the nozzle? Do I need to have the extruder mechanical endstop involved in this?  or that is only going to be used for auto level. And just so you know the picture did show up on my computer at home, like I said they have everything locked down on our work network.

Here sis the update:
I hooked the endstops up the way you said, and configured R-H to connect, both worked well.
I reset the firmware back to the link firmware. Configured MoBo 33 and the few settings I needed. Load firmware.
X or Y will home and stop at switch but wont move after that unless I reset the power. I did noticed that I can hear a very slight tapping sound coming from which ever stepper went home. I still can not get the Extruder or the Z axis to move, I thought maybe the driver was dead so I swapped the driver from Y to Z and Z still doesn't move and Y does. I swapped the z and extruder connector to the x and Y driver connectors and they both work. Its as if there is no instructions for Z and extruder to work? Would it help if I put my config h up here for you to see?
