Prints going through bed instead of upwards? - 7 years ago
Can anyone help? Hotend prints bed tries to go through the bed instead of upwards. Fillament feeds fine, everything homes correctly even with induction sensor. G28 and G29 work fine just when I try and print. Anyone ANY ideas?by BARRIE_K - Reprappers
Re: Hotend hitting bed using G29 - 7 years ago
Just found the problem.. Designer of the part gives these values #define X_PROBE_OFFSET_FROM_EXTRUDER 0 #define Y_PROBE_OFFSET_FROM_EXTRUDER 25 #define Z_PROBE_OFFSET_FROM_EXTRUDER 0 Which is correct if your looking at Pronterface X Y and Z axis but X and Y axis seems to be reversed in marlin so these are settings that work #define X_PROBE_OFFSET_FROM_EXTRUDER 25 #define Y_PROBE_OFFSET_FROM_EXby BARRIE_K - Reprappers
Re: Hotend hitting bed using G29 - 7 years ago
still if i send g28 and a test print its fine but its not probed for auto-bed leveling, if g29 everything homes and probe is not on the bed hotend just hits bed. looks like it might be an unsolvable problem and time to just check it all in the bin.by BARRIE_K - Reprappers

I added the + sign to see if it would make any difference but didn't. #include #ifndef CONFIGURATION_H #define CONFIGURATION_H #include "boards.h" // This configuration file contains the basic settings. // Advanced settings can be found in Configuration_adv.h // BASIC SETTINGS: select your board type, temperature sensor type, axis scaling, and endstop configuration //==================by BARRIE_K - Reprappers

I have got an MK3 Heatbed 214mm x 214mm probe offset from hotend settings are correct X_PROBE_OFFSET_FROM_EXTRUDER 0 // X offset: -left +right define Y_PROBE_OFFSET_FROM_EXTRUDER 25 // Y offset: -front +behind define Z_PROBE_OFFSET_FROM_EXTRUDER 0 // Z offset: -below +aboveby BARRIE_K - Reprappers
Re: Hotend hitting bed using G29 - 7 years ago
My issue is to do with firmware as sensor misses bed when using G29 but is fine when using G28by BARRIE_K - Reprappers

Auto bed levelling. hotend hits bed - 7 years ago
Ive built Prusia I3 Rework, but made modification by adding an induction sensor and using this modified part . All works fine until I use G29 then it tells me to home heatbed ect then it trys to home hotend but sensor is off the bed so hotends just hits bed. Anyone out there that can give me idea how to fix issue? I'm guessing its firmware but not sure what to change.by BARRIE_K - Reprappers

Thanks to everyone trying to help but nothing has worked and im finally giving up, in the bin it goes.by BARRIE_K - Reprappers
Re: not reaching correct temperature - 8 years ago
yep 12 volts 100% going to ramps board. As far as the motherboard type goes, #define MOTHERBOARD 33 is correct according to wikki Prusa I3 Rework build instructions and I tried #define MOTHERBOARD BOARD_RAMPS_14_EFB just to make sure, marlin says doesn't exist.by BARRIE_K - Reprappers

Oh and ive changed ramps 1.4 and mega2560 boards for new onesby BARRIE_K - Reprappers

this is the full config.h, Hope someone can tell me whats wrong. tried every number for thermistor #include #ifndef CONFIGURATION_H #define CONFIGURATION_H #include "boards.h" // This configuration file contains the basic settings. // Advanced settings can be found in Configuration_adv.h // BASIC SETTINGS: select your board type, temperature sensor type, axis scaling, and endstop configuratby BARRIE_K - Reprappers
Re: not reaching correct temperature - 8 years ago
no way of checking load on psu but I was using a JC POWER JC-360-12 psu just converted a 300W ATX pc psu and same things happening. in marlin im using number 11 thermistor. the thermistor i have according to supplier of prebuilt hot end is100K NTC B 3950 ±1% ,1m long. Think ive tried most of the settings in marlin now none seem to workby BARRIE_K - Reprappers
not reaching correct temperature - 8 years ago
I wonder if anyone can help. I've built a Prusia I3 Rework, all the motors and sensors appear to bee working correctly but the hot end is only reaching 160 and heat bed is on reaching 50 degrees. Can anyone help solve this problem as i've been trying for months now. PID just times out after a while at 160. I've tried everything i can find online and think of about ready to chuck thing out of thby BARRIE_K - Reprappers
