Ramps 1.4 Print Issue: Please Help! - 12 years ago
Dear Reprapers, Please advise. Attached photo. After finally getting extruder to work properly. The prints are now coming out weird. As per pic, you can see the layers keep moving up in Y direction on my. Ord Bot. Should I replace the Y motor? test? Has anyone experienced this type of bug. ? Any suggestions appreciated Janskiby Janski - Printing
Re: Printing Layer Error : HELP PLZ! - 12 years ago
The Ramps 1.4 board i have has an extra dual drive. I went and replaced the drivers from E2 to Y and uploaded the firmware. The same results. Can anyone explain to me what creates this behavior? When I tried to print a Box it resulted in type of stairs.by Janski - Printing
Re: Printing Layer Error : HELP PLZ! - 12 years ago
This process is not familiar to me. Can you explain? What are pots and 1/16turn is it the screw on the driver for Y axis? Turn left or right? Thanksby Janski - Printing
Re: Printing Layer Error : HELP PLZ! - 12 years ago
I have tightened the belts on Y axis and other axis. checked the 2560 board all looks find. anyone think it is the driver? too fast in Marlin? Please adviseby Janski - Printing
Re: Printing Layer Error : HELP PLZ! - 12 years ago
It basically moves the next layer up Y direction a few steps and continues to print proportionally to the move. HELP!by Janski - Printing
Printing Layer Error : HELP PLZ! - 12 years ago
So this happened: Finally after getting the extruder to grip properly, the prints are doing this: along 2nd or 3rd layer the print unexpectedly slides over and continues in the incorrect position. Please advise if anyone has encountered this issue Sincerely, Janskiby Janski - Printing
Extruder Clogging! Help PLZ
- 12 years ago
Dear Makers, I have the QUBD Extruder- Using NEMA 23 motor with standard gear. "at certain points during the print, the extruder valve spout clogs" This causes a miss feed and then it stops extruding. Has anyone had this issue with QUBD extruder? Please advise on solution -Janskiby Janski - Printing
Ramps 1.4 - MOSFET Q - 12 years ago
If a ramps1.4 boar short circuits due to wires touching. - In this case from D10 (extruder heater) - can the MOSFETs be replaced? See Pic I have bridged the shorted route and changed to a MOSFET up to 35watts to the Voltage controlling MOSFET, however, once I start it the temperature just starts going up w/o ability to stop. Overheating the board and all. Any advice on this problem? How hotby Janski - RAMPS Electronics
Ramps 1.4 Pins to pins.h in Marlin Q - 12 years ago
Could anyone explain to me the relationship between the placement of the pins on the ramps 1.4 board to the pins.h configurations. I am having a hard time understanding how to locate individual pins. For example My Motherboard = 33. why is "#define FAN_PIN 9" what does the 9 stand for? is there a map that can be superimposed onto the ramps 1.4 blueprint to match Marlin assignments?

Re: Ramps 1.4 to pins.h: need help! - 12 years ago
Yes! Thank you for the explanation. I was changing the heater pins instead heater and fan . Is there a map that explains the pins.h related to the board itself? For future experiments Sincerely JANSKIby Janski - Controllers
Re: Ramps 1.4 to pins.h: need help! - 12 years ago
What logic is the pins.h file following? Is it getting the numbers from another sub folder? Still new at this and having a hard time manipulating pins.h fileby Janski - Controllers

Hey there! How can I find out how the board matches the pins configuration/assigned numerical in the pins.h file? Trying to move the heater power down to D9 on the ramps board. Sincerely Janskiby Janski - Controllers

Re: Ramps 1.4 - Short Circuit Question- - 12 years ago
Quotecat.farmer . Does your fuse show sign of being burnt, the fuses are self reseting after they cool, unless it's been destroyed. I think you are safe to repair the board and apply power, worst case it does not work. If that is the case check the power at the fuse. The mosfet switches to ground..FYI. The fuse basically exploded in the middle of the D10 connection to MOSFET. Still new to the tby Janski - Reprappers
Re: Ramps 1.4 - Short Circuit Question- - 12 years ago
I played with the MOSFET pins.h settings and my method did not work. after I changed the pins.h settings back . the heater again instantly starts heating up and continues . I checked the temp on the MOSFET and it was very high 175-205 C. Is this normal or def replace the MOSFET? if so what type do I use for Ramps 1.4 boards? Best Regards, Janskiby Janski - Reprappers
Re: Ramps 1.4 - Short Circuit Question- - 12 years ago
It shows I am getting about 12.35 V to the board. #if MOTHERBOARD == 33 || MOTHERBOARD == 67 #define HEATER_1_PIN 9 #else #define HEATER_1_PIN -1 // EXTRUDER 2 (FAN On Sprinter) #endif #define HEATER_2_PIN 9 As per suggestions I looked into pins.h . is this the area for me to tweak I have allready reversed these values. Is this where I change D10 andby Janski - Reprappers
Re: Ramps 1.4 - Short Circuit Question- - 12 years ago
Hey Cameron , Since there is a visible blown fuse between D10 and the MOSFET, does the mean the MOSFET is damaged? I checked ohm of the MOSFET and it reads 3 ohms. The 2nd extruder MOSFET has the same reading. I am using a ramps fan and would like to keep it there without changing pins.h. Do you think a simple bridge would solve the heating issue? Or does the non responsiveness represents blowby Janski - Reprappers

Re: Newbie Question @ Hotend Temp Display LCD - 12 years ago
The Extruder is QUBD. Where do you recommend getting ball bearing idler? I will look but in case you have a good source. The hotend is a .4mm Nozzle and Using 40w 5mm Heater cartridge. I moved the thermistor to the tip of the Nozzle. This seems to achieve true temp of 230 at that spot. Now the LCD and the Nozzle read the same temp. Problem is with the Filament Feeder. I have not yet checkedby Janski - Printing
Re: MK2B Heatbed Question - 12 years ago
Dear cdru, Thank you for that explanation. I especially like the equation for wattage . The heat bed is fine then, it keeps temp steady at 110. Did auto tune on both heaters and now both seem to work fine. The extruder still needs so tweaks as there is a 2-4 degree variance when holding 230 for abs. Sincerely Janskiby Janski - General
Newbie Question @ Hotend Temp Display LCD - 12 years ago
Hey Makers, Current Ord Project is giving me 2 issues at printing stage: 1. Display of temp Heater Block vs Hot End Spout .4 is inconsistent. I have measured the temp of the tip of the hot end @ 200-230C . The Heat Block @ 256/260 maxed out. Do I have to move the thermistor to the end of the endstop extrusion spot or can I keep it between the block and the tip? My thinking is that it would theby Janski - Printing

I mean proper wire size for the heating bed?by Janski - Reprappers
Re: Pronterface / Slic3r Issue: Help!! - 12 years ago
Thank you for that explanation: I will try to use that gcode . I have abs so that will be : M104 S230. I just received a new cartridge 40w 5mm for the hot end. First try words well but I will need to auto tune it first. Do you know the proper gauge for the heating bed . I need 110C. Thank you Janskiby Janski - Reprappers
MK2B Heatbed Question - 12 years ago
Dear Makers, What is the optimal wire size for HeatBed? Currently using 14 gauge. Is that too thick? Heat bed is having issues with maintaining temp at 110.C Reason I ask is because the 40w 5mm Heater Cartridge I just purchased is either 18 or 20 gauge. Sincerely, Janskiby Janski - General
