Hello I have a SUMPOD basic wood printer with a Sanguino ramp board (board 62) and I cannot get it to work using the Marlin firmware that I could find on the SUMPOD web site. I am using the Repetier-Host software on my PC. I have spent 4 full days trying to configure it. I know the Arduino, C programming and ATMel micro controller very well (I am designing Arduino compatible boards) so it is becomming really frustrating but I do not like giving up. I have had to change quite a few thing on the configuration So far I can move the X an Y axis in the right direction and it stops and go slightly back ward when it reaches the endstop switches. The problem seam to be with the Z axis which goes from top to bottom, passes the switch, it clicks but it does not stop!!!! so makes a lot noise and I have to do an emergency stop..... Thos are my main settings #define INVERT_X_DIR true #define INVERT_Y_DIR false #define INVERT_Z_DIR true #define X_HOME_DIR -1 #define Y_HOME_DIR -1 #define Z_HOME_DIR -1 #define X_MAX_LENGTH 140 #define Y_MAX_LENGTH 140 #define Z_MAX_LENGTH 115 #define DEFAULT_AXIS_STEPS_PER_UNIT {84.88264,84.88264,800.00,60.0} Note that on the ramp I have removed one the jumper for the Z axis Can someone let me know what I am missing Attachments:

if z limit switch is arranged to be made when table is as far from nozzle as possible.. that is z max z plus makes the part taller ie moves the bed down..

also if your calibration is far off ( mine was by a factor of about two not exactly two oh no ~) then the return to zero for z will move too far...

in case this helps
#define INVERT_X_DIR false // for Mendel set to false, for Orca set to true #define INVERT_Y_DIR false // for Mendel set to true, for Orca set to false #define INVERT_Z_DIR true // for Mendel set to false, for Orca set to true #define INVERT_E0_DIR false // for direct drive extruder v9 set to true, for geared extruder set to false #define INVERT_E1_DIR false // for direct drive extruder v9 set to true, for geared extruder set to false #define INVERT_E2_DIR false // for direct drive extruder v9 set to true, for geared extruder set to false
// ENDSTOP SETTINGS: // Sets direction of endstops when homing; 1=MAX, -1=MIN #define X_HOME_DIR -1 #define Y_HOME_DIR 1 #define Z_HOME_DIR 1
#define min_software_endstops false //If true, axis won't move to coordinates less than HOME_POS. #define max_software_endstops false //If true, axis won't move to coordinates greater than the defined lengths below. #define X_MAX_LENGTH 140 //[SUMPOD specific, CHANGE FOR YOUR SUMPOD] #define Y_MAX_LENGTH 140 //[SUMPOD specific, CHANGE FOR YOUR SUMPOD] #define Z_MAX_LENGTH 117.5 //[SUMPOD specific, CHANGE FOR YOUR SUMPOD JCU]

Be cautious..you can mount switches - or + You can use + inputs or - You can invert the polarity of the switch ( no vs nc) You can make xplus move x minus..etc. But if you want your prints to not come out as a mirror image you need to get it right... So you can get it sort of working but wrong... Sorry but there are a lot of different ways to mess with the settings Z is perhaps the easiest because down is always z plus so....

The settings you gave me are they for the SUMPOD Basic printer?

They are the ones I use on mine...since you have x and y homing you should be good there. . My z height max is probably different since the hot end / extruder I made from the parts supplied ( at least three short) and knowing no different , is probably not what was intended..I in effect have a direct drive not bowden extruder...and my hot end heat sink is different now...still not 100% but until I remake the whole thing as good as the components supplied will allow...

Btw my sumpod (shipped long after the change to sanguino boards oh yes) was supplied with audrino and ramps 1.3 so I had to modify ( params) the latest marlin for sumpod....to get it to go at all...version control a chez sumpod is ..err...lax

unfortunatly this does not work for me with your setting X and Z are now worse. I have found a picture on the internet that show the axis directions Could you let me know if it is correct Attachments:

Also What should be the config in the Repetier host software? Attachments:

Welll...I seem to have x and y swapped relative to you.. And my machine homes to x = 0 and y= 0 z=117 I use the x - and y - and z+ inputs on the ramps board And use the nc and common pins of the limit switches..thus input goes high when switch made (or not plugged in..)... The firmware when homing moves towards the limit switch ..whenit sees the event it then moves away and looks for event again ( probably at lower feedrate to improve accuracy in determining trigger point) I remember but am not sure, having to move the y limit switch to the the other end as it was not at y =0... The swap of x and y ..well the sumpod build seems to have them wrong ie the labels of the limit switches In any case z is up and down..the y axis is the front -back ( if the solid wall is back) leaving x as the side to side..ie the stepper monted in the table is x and the one sticking out the top is y.. ..or at least that's what mine does ;-)

As to those repetier settings as far as it goes for size etc..yeah..but feed rate and temp..sorry kind of still working on those. .
