Hi I moved pc and then reconnected. I opened ground control and the full 2440 by 1220 came up . i thought this odd cause I am working with 48 by 48. The sled was not on center when I unplugged pc. Now I get the set chain length error. here is what i have tried: 1. shut down all and restarted, include unplug arduino. 2. tried different parameters all including 1219.2 1220, 2440, all variations. 3. re uploaded version (holey version) firmware . 4 tried other ground controls, the holey, the standard. 4. wiped eeprom 5. reset chains and immediately get error message. I re read the message about lost sled position and tried all. At one point the ground control after hitting stop to reset just goes dead. I have tried all i know and still can not get running. Please help, JR ps i am under on chain triangular and using the holey ground and firm. ---

Hi Jimr, When you need help like that, there are some valuable information you can share: 1. What is the set of events between the last time it worked, and the first time you noted it was not working anymore? Can you see something more than **just** moving a pc from one place to another? 2. can you set one ground control macro button to $$ then activate it to get the Firmware list the settings? 3. Then get and share the log.txt file of GroundControl. ---

pls tell me how the macro is set and where log file resides. i was running great, did the 6 hole config and sled centered and went right to top of board. cuttting fine. using 1220, 1220 parameters. I shut down pc. disconnected. I left the sled in a down left corner position. I started ground control again. this time it opened with the full sheet parameter and zero in center while sled was stil bottom left corner. ---

The log.txt file lies in the GroundControl folder on my Linux version. Hopefully the same for windows. About Macros: Open Maslow Settings and locate “Macro 1” and click on it to edit it. Type in: $$ then close close the settings panel then when you click on the upper right corner “Macro 1” button, Croundcontrol will send the $$ command to the Arduino. This will make the firmware send the list of EEPROM settings to Ground Control and dumped to log.txt ---

@Jimr, is this the same problem you were having earlier, when you couldn’t set the 12 O’Clock position? Here is another question. Before you started having problems, could you hear a difference between the two motors? It would be like one ran consistently, whereas the other one galloped, sounded quieter/louder as it spun. ---

I put new gear in left.not on rite. All gud till I moved pc and moved back. I got running today but optimized, holey, config, would not go to top again. U suggest I put steel gear I rite? What I mean is the holey optimization had [me.to](http://me.to) top o board. Now after the stoppage I’m back to low center and no move to center top of board. I did move ini. But put holey numbers in. To get to center I had to change vertical distance to 350 from 398.2. real vert is 430. ---

Joshua, can u please run the calibration for me? I cant seem to run it here. 1. 39 3/16 2 39 1/8 1. 39 5/16 2. 39 7/8 3. 27 1/16 4. 26 1/8 5. 27 6. 46 5/8 7. 47 7/8 8. 47 13/16 9. 46 5/8 10. 12 1/4 current settings: triangle feed is under vertical offset 360 (actual offset is 444.5, im trying to center up. distance between motors 3027.9 sled weight is 22.2 i set chain tolerances to zero for this new maslow.

yes it was, i got the final sled cut with maslow, however, after calibration the sled was 8 inches to low of center. so I went back to an old config on my other maslow to get sled higher
