100% New to repetier here. Help please (Page 1 of 2)

Well I use RH and slic3r on a sd4.  read through the manuals.
I expect the first thing you need to set is the firmware settings.  Steps/ mm on xy and z your heater pid
bed size and home position need to be set in slic#r and RH.
Hopefully some one with a davinci will chime in and give you numbers to start with.

Sorry you lost me. I flashed from stock xyz firmware

Thanks. I am going to install my b3 pico in a few days. What setting do I change to have the bed about 1inch lower when printing?

Ok thanks. Could you tell me what park position numbers might be? I would like the bed to lower about 6 inches or so after the print is done and the head return to the position above the filament waste box.  I have tried different ones but no luck yet.

Thanks. But how do I get the bed to travel down after a print? I set the park to park after a print, in printer settings but it does not seem to do anything after a print?

Hi here is what it shows. 

M104 S0 ; turn off temperature
G28 X0  ; home X axis
M84     ; disable motors

Ok thanks trying it now. Just two other questions and I think I have this repetier host stuff figured out. lol.
My fan speeds up and then slows down over and over again every 1/2 second or so. Ideas?  Also when trying to print a larger print the head goes to far and off the back of the bed about about 20mm or so? Not sure how to correct that?

Here is all the information you may have missed on what to do once Repetier firmware is installed and Repetier Host is installed. If you use Simplify3d you need to keep Rephost around to access the EEPROM settings of the Repetier firmware. That way you can make these changes and adapt them to Simplify 3d if you use it as well.

These settings should get you to where you print on the bed ans may solve some other issues.

on the Connection tab
connection = serial
transfer protocol=auto-detect
reset on connect= RepRapPro DUET Firmware
check box setting Use ping-Pong comunication

On the printer tab
Well this has less important settings but mine are as follows
Travel feed rate 4800
z-axis feed 100
default extruder temp 215
default heated bed 90
number of extruder 1
and all the other check boxes are checked

Tab printer shape
Classic printer
X Y ans Z homes = min

OK now it is 200x200 printable area but the print head has dead space off to the side for the cleaning area and so on.
But to make it easy just set x max 200 y max 200 and mins at 0 0. We will as a group come up with actual working numbers that are best and fill this in to what they actually need to be later. Please note that as expected these settings in the eeprom do not have a centered bed, considering we specified the homes at 0,0,0 this is to be expected. Again when more concrete numbers are found this will be edited.

That should be all that is needed to get the actual printer running on repetier.
That said I also put the z offest of -3.0 in the eprom in the config menu to allow for direct printing with No Z offset. Again this is not exact or perfect but works well for me on my set-up. Others add the z offset in slic3r. This z offset will depend on how you have adjusted the bed screws over the life of your machine and will not be the same as mine. So there are a few ways to set your z.

Use the auto leveling, to be discussed later

Manually adjust z table to be 0 as described here
ON YOUR PRINTER push the "OK" button and select "Quick Setting" and select "Home All". Once the print head "homes" itself, turn off your printer. This is done so you can easily move the print head to the four corners on the build platform. I had to lower the platform with the three bed screws before I could even move the print head on to the print bed. I adjusted all three screws so the extruder nozzle just touches the glass in all four corners of the glass. This should only be done after initially "homing" the print head as mentioned above. This gets the build table at its highest point where you fine tune the nozzle to glass clearance or lack of clearance.
With that done, turn the printer back on and push the "OK" button and select "Quick Setting" and select "Home All". You should now be safe to print with the proper clearance for the nozzle. contributed by chris
The only thing I would do differently in this is to use a piece of paper between the glass and the nozzle as a "feeler" gauge.

Edit eeprom config to be the 0 as it is. To do this,
Home machine. Use fast position menu to bring z to 10 and x and y to nominal positions for you to work with so that nozzel is above the glass working area, 50 50 should be good. take a scrap of paper and place it on the glass bed and lower the z till the paper just begins to grab in the gap. The z height is the negative value to add to the eeprom z position. IE my height was 3.0 I made z home position -3. Power cycle the machine. without homing and move the head around the build are to ensure there are no areas of dragging or excessive gaps.

Shouldn't the code a a letter Y in it not x?   Also I am trying to get the Z (bed) to be a bit lower in the home position but not sure how? I changed the Z home position in the EEMprom config but no matter what numbers I put in there the Bed still is at the same home position height?  confused

Thank you very much I did read it and tryed it, but the bed still is to high?

Sorry I was not clear. I am trying to get the bed far away from the z sensor. maybe a good 1 1/2"  away from the sensor when not printing.

gotcha.  thanks.
Do you know if there is a way to change the start path of the head? 
When it moves from home position and starts to print it hits the bed screw that is on the corner of the bed closes to home position.
