Hi, you can do that also in the Repetierhost menue configuration/ printer settings/ printer if the eeprom is activated in the firmware. The other possibility is to change the axis direction in the firmware that you have mentioned above. If you get an upload error you have propably not disconnect the printer from the computer befor uploading the compiled firmware, I think.
Good luck
Bernd

You have to get the first layer perfect. Without the first layer right, nothing else matters.Quote

I really have trouble to print something with my P802M; the filament do not attach well so just at the second pass a part of the printed PLA goes away attacched to the nozzle.. any suggestions?

Yes if you set up for your machine. Start with an existing profile from Cura or the like and copy the values over. My computer took a dump on me so I lost some settings, and had to print replacements for my cracked motor mounts.Once I get it moving again, I'll work up a starting profile. Have been having inconsistent bed leveling.Quote

Simplify3D is compatible with P802M?

Hi wotwood
The resistors are urgently needed to et the output Voltage to the right level . Or you cn buy a sensor from Zonestar where the resistors built in. There are different types of sensors (NPN or PNP is easy to say the switching direction) usually I think it NPN, but not at all you can adapt this in the firmware. If you do it like this guys, it will work.

Post a link to the one you purchased. The screw holes on the ones I have found do not fit the P802.Quote

Well I just ordered an aluminum Y carriage because my acrylic carriage is warping about 1/4" once it hits 115 degrees. Sometimes it would stay straight for a while and warp mid print screwing it all up... So upgrade time. I also ordered all the parts to do the Z axis upgrade to using just 1 Z axis stepper. as I found my Z was off level about by close to 2 mm frequently.

I have never used a mac so I can't address your issue with first hand knowledge. On windows you have to install FTDI drivers before the computer can see the Melzi board (FTDI has a driver for the USB chip on the Melzi). This is the link to the FTDI drivers [www.ftdichip.com] so you can select the proper driver and instructions for your MAC. On windows after installng the driver the printer will be on a USB port you can select.
Hope this helps.

I installed the driver but as before i can connect but i can't send command; attached image could help.

I solve by myself; i had to set the baud rate to 115200!

Hello everybody
I also have a P802M, and i have bought a sensor for auto levelling.
It's a Baomain LJC18A3-BZ / BX 1-10mm Capacité Capteur de proximité Commutateur NPN NO DC 6-36V 300mA.
I have create a support to use it.
Now the problem for me it's the configuration.
I have use your firmware gwc2795, and i thank you to have shared it with Google Drive
Here my Probe configuration :
---------------------------------------------------------------------------------------------------
// #################### Z-Probing #####################
#define AUTO_LEVEL_DEBUG 0
#define FEATURE_Z_PROBE true
#define Z_PROBE_BED_DISTANCE 4
#define Z_PROBE_PIN ORIG_Z_MIN_PIN
#define Z_PROBE_PULLUP 0
#define Z_PROBE_ON_HIGH 0
#define Z_PROBE_X_OFFSET -26
#define Z_PROBE_Y_OFFSET -48
#define Z_PROBE_WAIT_BEFORE_TEST 0
#define Z_PROBE_SPEED 2
#define Z_PROBE_XY_SPEED 200
#define Z_PROBE_SWITCHING_DISTANCE 0.3
#define Z_PROBE_REPETITIONS 2
#define Z_PROBE_HEIGHT 6
#define Z_PROBE_START_SCRIPT "G28 Y0 X0\n"
#define Z_PROBE_FINISHED_SCRIPT "G28 X0 Y0\n"
#define FEATURE_AUTOLEVEL true
//#define Z_PROBE_X0 80
//#define Z_PROBE_Y0 80
#define Z_PROBE_X1 90
#define Z_PROBE_Y1 90
#define Z_PROBE_X2 100
#define Z_PROBE_Y2 100
#define Z_PROBE_X3 110
#define Z_PROBE_Y3 110
---------------------------------------------------------------------------------------------------
When i use G29 in Repetier Host, the probe doesn't use my first point (Probe X0 and Y0), the extrudeur go to HOME X and HOME Y, then it go to approximatly X150 and start levelling (But at HOME Y, the probe is out of bed :/ )
I don't understand why the extrudeur doesn't go to X80 and Y80 and then star levelling when i use G29.
Could you please help me, i don't know what i have to do
If you have any question, or want any parameters i have, that can help me to solve this problem, i will copy you here.
PS : Sorry for my bad English !
Damien

What are your typical slicer parameters?
Layer Heigh?
Perimeters?
Fill Density?
My goal is to reduce the "aliased" effect
Another goal is to limit or reduce to zero the "not coveded" zone of first layer
Any ideas?

I change the slicer parameters based on filament and the item being printed
Layer Height 0.2 (usually)
Fill density 20 - 100 depending on object
I don't understand the not covered question
I have found I have to match the temperature to the filament and object being printed to get the best result. Most temperatures are in the 200C range.
