I was able to leave acceleration on doing the things i mentioned in my previous post. I really haven't noticed acceleration helping or hurting much at all, but I've also have only been printing at a speed of 16mm/sec. Possibly acceleration would have more of an impact when printing at higher speeds to reduce under/overshoot, but I'm not sure. Chad Cby Chad C - Skeinforge
Nix, I believe the issue is stemming from how the firmware processes the code. It's almost as if the firmware doesn't process a whole gcode line at once but rather processes each individual command separately. In your example code, the last "F" value given right before your Z axis movement command is "F2400.0" which sets the speed on the mainboard to 2400. Next, your example code moves the Zby Chad C - Skeinforge
Sure, send what you have and I'll take a look. Thanks in advance, Chad Cby Chad C - Skeinforge
I currently have Skeinforge set to a maximum Z axis speed of 0.5 mm/sec. The code for that actual z axis move is generated correctly, but there appears to be somewhat of a gray area between the printer mainboard firmware requirements and the skeinforge gcode requirements. I've been trying to create a batch file to post process the skeinforge exported gcode to add the G1 F40.0 line before any Zby Chad C - Skeinforge
Just a thought, Anyone have a Microsoft Word macro that will insert the G1 F30 command right before any line where the Z value has changed?

I appear to be having this same issue as the root of all things wrong with my mendel. I'm using the techzone remix electronics. I've tried inserting a M105 homing code which is added correctly. I've also tried replacing all M103 commands with different variations of the "M103 ^p G1 F30.0" and "G1 F30.0 ^p M103" commands but the code itself is always inserting some movement right before the actby Chad C - Skeinforge
Now that the X and Y axis have been mentioned, I haven't really calibrated the X and Y mm/step in the firmware. I have steppers that are 0.9° per step instead of the standard 1.8° and just doubled the mm/step numbers originally. I've noticed that my 20mm calibration cubes come out to be about 20.5mm x 18.9mm. I did go ahead and tighten down my X and Y axis belts and increased the torque yesterby Chad C - General Mendel Topics
I recently printed the Simple Spool Hub from Thingiverse.com and noticed that my circles aren't coming out perfectly circular; they come out egg-shaped to some degree. It's probably hard to tell in the attached picture. Does anyone have any suggestions as to how to fix the non-circle circles? I'm printing with PLA and am using skeinforge. Thanks, Chad Cby Chad C - General Mendel Topics
The x and z axis were both loose but i couldnt get the y axis pulley off so i assumed it was fine. The stepper control boards have also slowly lowered their power setting over time i believe as they were a bit underpowered. i corrected both of these and it seemed to fix the problem. Thanks for the help, Chadby Chad C - General Mendel Topics
Correction... both the X and Y axis shift on the first layer.. It prints the perimeter fine then when it starts doing the infill, it moves over and ruins the print quite quickly. Chad Cby Chad C - General Mendel Topics
Recently, I've noticed that my prints have start to shift a bit after the first object layer. By "shift a little bit," I mean that starting at the second layer, the print head seems to print the object from then on with about a 1-2mm shift on the Y-axis. After this first layer shift, the print finishes fairly well. The shift happens regardless of the gcode having the base layers (raft) being turnby Chad C - General Mendel Topics
I went through a similar situation as Brad. Kymberly and Lambert at Techzonecom.com are highly recommended from me as well. They definitely aren't afraid to pick up a phone or send emails as needed to help their customers out. If I had to it over again, I wouldn't have dealt with Botmill at all. Do yourself a favor and order from Techzonecom.com Chad Cby Chad C - General
I confirmed with Lambert of Techzonecom.com that their Generation 3 Electronics are shipped with the Thermocouple A/D firmware already installed. I attached a picture showing my setup for the mainboard and extruder controller. I hope it helps some. Chad Cby Chad C - General Mendel Topics
I talked with Lambert from Techzonecom.com about a week ago and was told that the firmware on the Techzone extruder controller was shipped with the thermocouple firmware already in it which is why ordered it for the most part ( I didnt want to mod any firmware/software). I'll try this out tonight if I get a chance though. Thanks, Chadby Chad C - General Mendel Topics
I recently was finally able to get my stepper motors on my 3 axis to move correctly and now it's time to move on to mounting the extruder to the gantry. I ordered the Tech Zone Remix Thermocouple Kit with A/D along with the Extruder Tip Parts Kit which includes a small oak wooden block. I'm supposed to mount the nozzle to the bottom of my extruder (I'm using Adrian's Extruder) but I cannot find gby Chad C - General Mendel Topics
