Hey everyone
Anyone have a copy of firmware, that works with ramps 1.4 with the reprap smart discount lcd?  with the configuration h. already configued, for the frankedCube?
Please, and Thanks

Got My Franked Up Cube, going, had to make a print bed, original bed fell off table.. printed 10mm calibration cube, everything looks good.. I like to have it print in the middle of the bed, anyone know how I can do this??

Thanks again Dan & Spegelius

Hey spegelius, I found the speed setting. Thanks
On the z axis, we have it as Z max, are we supposed to have reversed the motors direction? I just notice now from Dan picture, the black and green wires are reversed, i didn't see that and assumed,  all motors wired the same.. Is this right?
Thanks again.

No problem, i'll answer the best i can.
I'm not sure if changing the z endstop fixes that, but shouldn't hurt to try it? Seems strange to me that z is moving so fast. On myp rinter, it's really slow when moving in Pronterface or in LCD controller. What is your speed setting in Pronterface?

Thanks again.
 Pronterface has speed settings? where would I find them?, I thought maybe it was the Step per mm, in the config h file?

Hmm it seems to me that your endstops aren't wired correctly. I put them to the tip pins shown in here: http://www.reprap.org/mediawiki/images/0/06/RAMPS_dossier.pdf; xmin, ymin and zmax.

 Your right, I had my end stop x-min y-min z-min,  Will this stop my z axis from raising the print bed 100mph?  z axis is super fast, almost broke my bed. I took the bed off for now, until I get this right..
 I'm sorry to be asking you so many questions, I am also googling a lot of info as well.
Thank you again

Did you pull the latest version of the configuration? I made a new commit that moves the origin to the corner, which should allow you to move it freely

No I didn't upload the latest verison, I thought the only change was the SD card support, I will upload and let you know, a little later.. Thanks for all your help.
I just tried it, I don't understand, why my x, y, z, axis are only going in one direction, if I try the other direction, pronterface says endstop hit.. I also tried to raise my Z axis up 10mm and it went so fast all the way to the top, and kept trying to go..  You are saying you are getting good prints with these setting??
 I don't understand what im doing, wrong..

 Thanks spegelius, I got my ramps to work with your marlin Rc..  But I have to ask you something, when I try to move my X axis to the Left going towards the end stop, Pronterface says endstops hit:  X:2.99   The X axis will move to Right no problem, but when I try to move it back to the endstop, it wont let me, is this normal?
Also when I hit Y+ the bed moves forward, but when I try Y- the bed wont go back to the endstop, is this normal??
 Can you tell me does the  X,axis  control the extruder  from left to right?, and the Y controls the print bed going forward and back?,  is this right?

Yes, X is left to right and Y is forward and back.

What is your X and Y position after homing them? When i had bed 0,0,0 position set to bed center (BED_CENTER_AT_0_0), X and Y where showing -71 on the LCD screen. Now that i've commented out BED_CENTER_AT_0_0, X and Y are 0 after homing.
My configuration are the same as in the marlin Rc you uploaded?  I figured you and I have the same printer, so there all configuration h setting would be all calibrated, but when I try to make my Extruder go left from the middle, the software says that my endstop is being triggered I guess, because it wont let me go left at all.  also my Y axis the print bed will move forward but wont go let me move it back towards the endstop..  any idea what I am doing wrong?

Yes, it's RAMPS1.4 and A4988 drivers. I have tuned the vrefs to ~0.25V for X, Y and Z. For E i'm using ~0.94V, it was skipping steps with lower vrefs and by calculation this should feed the max amps the stepper can take (not a Cube stepper, mind you).

For the extruder steps, i set it to 147 instead of 80, can't remember the name of the variable (STEPS_PER_UNIT perhaps?)

The controller i'm using is http://reprap.org/wiki/RepRapDiscount_Full_Graphic_Smart_Controller. If you have different controller, you need to comment out #define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER from the config and uncomment proper line for your LCD/controller.

M82                               ;set extruder to absolute mode
G28                                ;move to endstops
G1 Z15.0 F2500             ;move the hotend to 15mm
;G92 E0                           ;zero the extruded length
;G1 F200 E10                  ;extrude 10mm of feed stock
;G92 E0                           ;zero the extruded length again
G1 X0 Y0 Z0.4 F1000    ;move Z close
G1 X50 Y0 Z0.1 F1000  ;move 50mm to right and Z closer

End g-code
Code: [Select]
M104 S0                                      ;extruder heater off
;M140 S0                                      ;heated bed heater off (if you have it)

G1 E-1 F300                                ;retract the filament a bit before lifting the nozzle
 to release some of the pressure
G1 Z+0.5 E-5 X-20 Y-20 F2000 ;move Z up a bit and retract filament even more
G28 X0 Y0                                   ;move X/Y to min endstops
 so the head is out of the way
G28 Z0                                        ;home Z
G90                                             ;absolute positioning

Also updated configuration in github. Needed to enabled sdcard, now it's printing from it
Spegelius Thanks so much for this..
Are you using Ramps 1.4 with the A4988, ?  also what Lcd panel are you using?? I actually put your values from the config h, into the marlin i'm using.. I couldn't get my Reprap smart controller to work with the RC..  If you are using the A4988 drivers, did you dial down the voltage?  just wondering.. 
I just getting things to work out, thank to you past reply, I calibrated my extruder, though x axis seem to move slow, and the z axis is super fast..

Thanks spegelius
Yeah I just keep hitting walls, when I first started this project, I thought just have to wire it up and install the custom firmware, and would be good to go.. I going to try your config..  I'll post back, if any luck..

I uploaded last night, but can't get my full graphic smart controller lcd, to work with the firmware.. I tried  #define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER
  and #include <U8glib.h>
The lcd shows the menu, but I can control anything, the knob on the lcd, if i press, or turn it, it wont control through the menu.. 
Hey spegelius,  do you know, if you can take a configuration h, file from one marlin firmware, and install it to a different marlin firmware??

No progress with the printer, had other errands to do whole day, but i forked the Marlin github repo and pushed my Cube2 config there: https://github.com/spegelius/Marlin. Use branch Cube2_RC. It's based on 1.1.0_RC6 as i forgot the switch to stable branch before starting... well time will tell if the RC is has bugs
Thanks spegelius

Thanks. When you get the z-offset figured out, do post it here as i'm unsure about it myself. If the offset is set in firmware, it's going to be a PITA to set as i'm planning to run prints from sdcard and not have PC connected to the printer...

I did the wiring and no smoke :). And it's working, partly:
- nozzle temp is read correctly and it heats up
- X and Y axes are moving, had to flip the connectors, though
- endstops for X and Y work, i can home the axes.
- fan seems to get power, but i need to remove the resistor i have installed (needed it because the fan is 12V and Cube uses 24V)
- LCD and controller works, haven't tested sdcard slot yet

Not working:
- Z doesn't move. Actually i can't even input a mm value with controller. I suspect that this is simply a misconfig i made in firmware, need to check that.
- E doesn't move, even though i can input movement length with controller. I need to check the wiring. The extruder stepper motor is not the default Cube motor, but i works with Cube's motherboard. I bought a new motor when is installed the Airtrippers bowden extruder because Cube's motor didn't have long enough axle and the drive gear is really stuck on it anyway.

Both Z and E get power to the connectors and all the A4988 drivers have proper vref voltages (needed to tune them down, by default they give 0.63V which is too much).

Some pictures of the messy setup which i hope i can get cleaned up later: https://www.dropbox.com/sh/qyosfww7zud15l4/AAAp6i1h_ljRp9sGNML-bRyya?dl=0
I was having alot of problems with the Marlin firmware, so I tried the Repetier Firmware, the download page, let you configure the firmware before you download it, and it explains what all the different values are, which for me being new to the 3d printer world was great..
 Everything was moving as it should, after the upload..
I'm using a mk8 extruder china clone version, and instead of extruding it just makes a clunking nosie, also the hot end says it heated up, but still cold, I think i might  get rid of the mk8, and get a E3D J-head Hotend 1.75mm..
Check your E and Z  max acceleration,  in the configuration h, make sure it's not set to 5000, if it is, set it to 1000, This worked for me when my Y axis wouldn't move with marlin..

Heh, yeah Dan has been MIA for a while. But he did leave good instructions, shouldn't be too hard to figure stuff out.

About calibration: i think that what is mostly needed is to tune the DEFAULT_AXIS_STEPS_PER_UNIT. I'm using
Code: [Select]
#define DEFAULT_AXIS_STEPS_PER_UNIT   {80, 80, 80, 80} as that's what Dan has in his firmware and it should work with the A4988 stepper drivers. If not, then just change those values until it produces proper movements. Another thing is the Z-axis offsets, but as i haven't used Marlin ever before I don't know if there's a setting that can be tuned without changing the code and re-uploading the firmware.

Also i'm using latest stable version of Marlin firmware and that's bit different compared to what Dan was using. I think i got the values set up right, but that's to be seen when i get enough time to finish the installation, maybe this weekend.
Thanks my friend..   and I agree Dan did leave good instructions..  Thanks Dan.
Hopefully you stick around, just in case I get stuck..
I am now seeing if I can get the z axis offset, and maybe try my first print, in the next day or so.. good luck spegelius, with your project.

Thanks spegelius

That did the trick, like you said no wires attached just the ramps.. One of my endstops was shorted because of a solder break.. Do you know if the frankencube needs to be calibrated after the ramps is installed?    if so I need to find a  Caliper..

Thanks again,  I think I going to do a missing person report on Dan..lol
