Isn't it compatible with the newest Merlin-software?]]>https://www.soliforum.com/user/69/2012-11-16T21:47:55Zhttps://www.soliforum.com/post/4937/#p4937<![CDATA[Re: Round corners]]>Give it a try in Skeinforge. I've had perimeters do slowdowns in seemingly random places, and I don't know if it is gcode or firmware. Do you have a different speed setting for small perimeters? Maybe it is treating that inner radius as a separate small perimeter.]]>https://www.soliforum.com/user/14/2012-11-16T20:42:45Zhttps://www.soliforum.com/post/4920/#p4920<![CDATA[Re: Round corners]]>Yes, will try the cube-test. Take a look here, the head moves very strange and slow in the inner corner-radiuses there, is this normal? http://www.youtube.com/watch?v=eeeGz_2p … ature=plcp]]>https://www.soliforum.com/user/69/2012-11-16T20:30:38Zhttps://www.soliforum.com/post/4918/#p4918<![CDATA[Re: Round corners]]>Try the cube test, that might give you a solid number to work with.]]>https://www.soliforum.com/user/14/2012-11-16T20:05:56Zhttps://www.soliforum.com/post/4908/#p4908<![CDATA[Re: Round corners]]>The repetier shows "perfect" roundness. I uploaded the newest firmware and added M99 Y0.1, but that was too much. Will try a lower value now.
I'm using 0.1mm i Z-lift, has this influence on this?

That would tell you if it is gcode, or the printer's execution of it.]]>https://www.soliforum.com/user/14/2012-11-16T18:51:20Zhttps://www.soliforum.com/post/4879/#p4879<![CDATA[Re: Round corners]]>Thanks Ian. I turned the model 45º, but the problems seems to persist. I also tried to fix the model in Netfabb, but same result. I will download the latest version from Lawsy and add the backlash.

Turn the model 45 degrees and see if it turns out any differently. If you have backlash, it should show up in a cube. If the X dimension is right on, and Y is short, then the amount it is short should be your backlash. If you have Lawsy's latest firmware, you can use the hysteresis compensation. Enter M99 Y[your backlash amount]. If it works, you can enter it for good in firmware, or add that line to your start code.]]>https://www.soliforum.com/user/14/2012-11-16T16:58:26Zhttps://www.soliforum.com/post/4852/#p4852<![CDATA[Round corners]]>I have troubles with the last prints with uneven round corners. What could cause this? The head goes very slowly in those areas. Perimeters: 70mm/s Small perimeters: 50mm/s
