Re: Moving from Marlin to repetier failed! - 8 years ago

It's trying to move too fast, I don't know exactly where it's trying to go in such a hurry but try limiting the maximum Z speed to 3 - 5mm/s

Re: Pronterface Custom Setup - 8 years ago

Mine automatically saves the window position and the sizes of the individual sections on program exit. The settings are stored in your user profile directory in either .pronsolerc or in my quick test printrunconf.ini for the precompiled version.Yours may be different since I just compiled it into an exe myself but your user profile directory should hold the settings files. If you can't see them,

Re: G-code Handshake Between Host Software and Marlin? - 9 years ago

Pretty sure the host just waits for Marlin to spit back an "ok". This isn't a pronterface specific question though, you'd probably get more relevant info posting in the firmware section.

Re: No negative z-axis using console - 9 years ago

Settings -> options and untick "clamp manual moves". Also if your printer thinks it's at 0 already then the firmware itself might not let you move in negative values.

Re: How to determine which thermistor I have? - 9 years ago

Quotemrmuffin I tried using the auto PID calibration but my thermistor is still reading much higher than what the hot end actually is. I'm using the setting stated in the guide (#5 in marlin configuration.h) but the temperatures still arent right. For example when running the pid auto tune at 150c the hot end was only about 70-80c. PID tuning doesn't adjust the measured / actual temperature, all

Quotefrankvdh QuoteI don't have a probe, it's just got the simple switch. As far as I can tell, it seems to occur no matter where X and Y are currently. So would I be right in assuming I have to figure out where my problem with the Z endstop is? I'm guessing I've got 3 possibilities - 1. it's connected to the wrong pins on the board, 2. the switch itself is faulty, 3. there's a problem with the w

Re: Unresponsive Z-axis end stop and wrong homing direction - K8200 / Repetier Firmware - 9 years ago

Chances are your Z endstop is reporting triggered. What it'll do (well marlin anyway) is move down until it hits the end stop and then move up until the end stop opens again and then back down at a slower rate to ensure an accurate homing. I'd say your z endstop is either wired wrong or plugged in to the wrong port on the board.

Re: Unresponsive Z-axis end stop and wrong homing direction - K8200 / Repetier Firmware - 9 years ago

As I said in the other thread. Does moving it up manually make it move up or down? If it moves in the direction you tell it to and it just homes the wrong way you can set it in the firmware to either home to min or max. K8200 should home all the axes to minimum. It's a single check box in the rep firmware config page. Check you've set it to home to the correct spot.

Re: Post subject: @$%&*#! Nearly ready to throw the printer out the window! - 9 years ago

Marlin now has an option to use the end stops full time. I have the hardware endstops turned on with software endstops disabled because I have min and max end stops. Even if I tell my printer to move to a location it can't move to it won't go and grind on the end of its travel limit because it hits the limit switches and just stops. I don't know how recent it is but it's in the 1.0.2 release ver

Re: Pronterface interface issue on raspberry pi - 9 years ago

In your home directory there's a file called .pronsolerc, it's hidden so you'll have to enable hidden files to see it if you're in some sort of GUI, otherwise in a terminal window just open it with your favourite editor (for me that's nano) e.g. nano ~/.pronsolerc

Re: Post subject: @$%&*#! Nearly ready to throw the printer out the window! - 9 years ago

Marlin by default I believe ignores the end stops because if you have cross talk between the end stop switches and your motor wires it can cause a false trigger and stop the axis moving mid print. As for the homing direction, look in configuration.h for these lines #define X_HOME_DIR -1 #define Y_HOME_DIR -1 #define Z_HOME_DIR -1 and make sure they are all at -1 (home to minimum). I believe som

Re: Build your own 3d printer class - 9 years ago

QuoteThe goal would be one class, one printer kit, e.g. everyone builds the same printer, to get people up to speed. Also should mention that the intended audience isn't the person who doesn't know a phillips from a straight edge. There is a prerequisite of basic knowledge.. If someone is knowledgeable enough to build an entire printer kit within a day then they certainly don't need your class.

Re: New to firmware. Which is the latest stable version of Marlin, and where can I download it? - 9 years ago

You're all insane, I just compiled Marlin v1.0.2 using Arduino v1.6.5 on windows 7 x64 with no errors. To the OP: Make sure you're properly configuring everything and you have the correct motherboard selected and that you have the correct board and processor selected in the arduino ide. If you use a full graphic LCD panel you might need the u8glib

Re: Pronterface issues - 9 years ago

Not every file is changed when a new binary is built so if there's nothing wrong with the original file, it might even date back to a few years ago. I prefer to run the files directly from source myself, let's me tweak stuff to my liking. Down side is you need python and its dependencies installed.
