OK, so I am a bit of a noobie so please don't yell at me. lol I have my first decent print and everything seems to match my numbers in Slic3r except I have a few questions on how to get things a bit smoother. Machine: DEFAULT_MAX_FEEDRATE {500, 500, 5, 45} DEFAULT_MAX_ACCELERATION {2500,2500,50,5000} DEFAULT_ACCELERATION 1000 DEFAULT_RETRACT_ACCELERATION 1000by uMinded - Slic3r
I have a few issues with my set up I hope someone can shed some light on. My printers zero coords are X Right, Y Front, Z Down. My settings in printer shape however have the "origin dot" in the 3d view in the front left of the screen causing the whole thing to mirror funny,.. My settings are: Home X: min, Home Y: max, Home Z: Min, X min: 0, X max: 165, Bed Left: 0, Y min: 0, Y max: 200, Bef Fronby uMinded - Repetier
So I solved all of my issues. Some wrong firmware settings, I had a few wrong settings and a broken wire half way to one of my motor phases so it was giving me random errors based off what bumped what. I have a question though, If I command an axis to move say X10.00 and do that 5 times the axis moved 20mm then starts to pulse more and more rapidly until it stops at 50mm. Its accurate but the puby uMinded - Repetier
Well I found a bug in the firmware but I still have not solved my problems. SEE HERE FOR BUG REPORT I uploaded v0.71 and now not much of anything works... My LCD works well and in the host software I can issue M115 and M205 and get responses. I can even set echo and dry run and watch them changed under the LCD menus but I can not make any driver step and none of the mosfets turn on! Its almost lby uMinded - Repetier
At full stepping I have 430 steps/mm and at 1/2 microstepping it is 860/mm. I downloaded a fresh copy of the firmware (0.71) off the website as I was using one from my other drives and it might of had a botched configuration or something strange going on. I went through and put in my calculated steps/mm on my axis and will try it out when I get home tonight. Does anybody know a good method onby uMinded - Repetier
I changed my extruder to 1/2 stepping to dampen any oscillations I might of had, Feedrate: 20, Max Feedrate: 60, Acc: 8000 and I am running the extruder without filament. The motor now turns when commanded but theirs a lot of interference and 1/20 steps it goes the wrong way. I hooked that motor to the X axis and I can move it no problem. I swapped drivers and its fine on everything except theby uMinded - Repetier
I just built a new RepRap out of 80/20 and was trying to set it up all night without any lock. Everything is skipping and nothing is working right. Problem #1) I have the latest version of Repetier firmware on my Mega 2560 and the Repetier Host for linux working. I can open a serial terminal to the arduino at /dev/ttyUSB0 @ 256000 8-N-1 as a normal user. I have the host set up to use that tty buby uMinded - Repetier
My jitter problem occurs at any current level. If my motors are unmarked how am I to calculate what current level to set them at? I just turned the current down to nearly zero and then back up until the axis moves smoothly to set my current levels. I tried running the Z with nothing attached and with a load on it and still the problem occurs. How would I go about mirroring the Z signals onto theby uMinded - Firmware - mainstream and related support
The current is set at 30% (so 333mA) and the motors are running off 12V. The Pololu has a heatsink on it. I tried to scope the signals but their to intermittent to get a clear capture. I took the Pololu off my X and put it on the Z and did the same with the motor connector. When I command the Z to move I get the jittery behavior still. I lowered the current to almost zero and it still give theby uMinded - Firmware - mainstream and related support
I am running Marlin 1.0.0 RC2 () on a Mega 1280 with Ramps 1.4 board. I have a major problem with my Z axis stuttering around and the driver is overheating! I command the Z to move and it will freak out and wiggle back and forth and after stopping the idle current through the pololu will cause it to get really hot. I am testing this with the stepper not connected to anything at all. The motor isby uMinded - Firmware - mainstream and related support
I have built a RepStrap in the form of a Mendel and am getting the electronics working. I have built some stepper controllers out of some awesome Toshiba 3.5A boards and have HEXFETS to control my extruder and bed. I was looking around the latest Teacup Ramps config and noticed that they have the end stops listed as min and max. On my CNC machine all of my axis limits are wired in series as froby uMinded - Firmware - mainstream and related support
