Rambo Servo Setup for Auto Bed Leveling for Noobs

[adamfilip]

i ended up moving my x and y ends stops in so that it wont overhang
but now when i try to home Z it says "z probe out. Bed"

[sniffle]

So i talked to @EvdZ|Ultimaker on the #marlin-firmware irc channel, he told me to remove the decimals to make it a whole number, the exact positioning of the probe is not critical. which somewhat makes sense and makes computations easier. and when i did this that fixed the problem.


this shoudl be your offset

#define X_PROBE_OFFSET_FROM_EXTRUDER -51
#define Y_PROBE_OFFSET_FROM_EXTRUDER 8
#define Z_PROBE_OFFSET_FROM_EXTRUDER -10

ok i will try that. i noticed that im recently getting upload errors

Binary sketch size: 162,052 bytes (of a 258,048 byte maximum)
avrdude: stk500v2_recv(): checksum error
avrdude: verification error, first mismatch at byte 0x10f50
0x31 != 0xdf
avrdude: verification error; content mismatch

That isnt the compiler it is to verify what you jsut compiled, that isnt something that i can fix or find out about. I compiled it no problem after changing the values

and EvdZ is one of the primary developers of Marlin right now, and obviously works for ultimaker as well

here is my current Config.h file
i will post a video of how the system is working right now
in a few min

right now there is a large space between the hotend and the bed, after it completes the ABL

[sniffle]

there will be a space between the hot end and the bed if you are running G29 stand alone. Try doing a calibration cube or something small with G29 added to the custom G-code after the G28 and see if it prints properly.

That's odd that your having trouble with it flashing the memory, Just to cover all of your bases be sure to use the short USB cable provided by Colin, because interefence can be had with longer cables, If that doesnt help there is a chance that there could be an issue with the flash. If that's the case contacting Colin for a replacement board will be your only option just test extensively

i did restart Arduino and it uploaded fine
I do have a long usb cord, but i need it to reach my desktop machine

very nice, Where did you get your glass? I'm using the 2ml 3$ a sheet glass from lowes, and i have a LOT more clips on mine than you do mainly to hold the heater to the glass more securely so that it will heat up more evenly
