When I jog and its on 1mm it moves at least 10mm. I think that I had better start again. Have refreshed and now the columns are blank
Did you remember to close EaselHost (the part of easel running in the systemtray?) something seems to be hijacking your serial data Old settings are in your screenshots above luckily
Just deleted and uploaded openbuilds again and $110 and $111 are showing at 500. Should I try at these settings or put them up to 5000 each as you suggested?
Your screenshot had 10000 in them yesterday, which is definately too high Grbl default is 500, see gnea/grbl but 500 is super slow (many jobs run faster) - so yeah, set it to 5000
Very normal for MDF it is just dust held in a board form with resins cannot speak to the Aluminum sounds about right though.
Hi Peter Just found that the default settings for $110 and $111 is 1000 and for $120, $121 and $122 is 150.
Not the default, the OBControl 1510 profile. But thats too high (you skip steps), Set it to 5000 please.
Thanks Peter Will do. When I have sorted this problem I will want to send you something for your trouble.
Moving (Feedrate) too fast can ruin bits. But also moving too slow (causes heat build up) Clearing chips and cooling the endmill much prolonga life. If you have an air compressor, a small nozzle blowing out the chips and cooling the endmill is a quick win
The last cut I made the edges were very rough. Can you point me in the right direction on this one please?
- Speed and feeds - endmill type (o-flute, upcut, downcut) - use a finishing pass in your CAM - pictures help - so we can see whats up
Try using a straight flute endmill/router bit. I use only double straight fluted endmills for wood and I do not get tear out/rough edges. You should ramp into the material. For my depth of cut in wood and some plastics (HDPE) i use 1/2 the endmill diameter. So, for a 6mm endmill I cut 3 mm deep. For wood I cut at 2500mm/minute and it works well. Maybe you should try starting at 2000mm/min, or less, because your machine is larger and most likely not as rigid as mine. As Peter said, lead a small amount for a finishing path. When I do a finishing path I will leave about 0.2- 0.3 mm and I will cut it at full material depth. This cleans it up nicely and removes endmill marks from the roughing passes.
Thank you so much. I am a complete novice but boy have I got the bug!! Keep safe from your friend in the UK
After adjusting feed and plunge settings, checking all of the belts and making sure that all is tight most of the problem has gone. I am still getting around 0.25mm over cut on the x axis. I have tightened belts and have noticed the following. Y AXIS. Undone belts and moved gantry forward and back without any problem. After connecting belts it is the same. X AXIS Undone belts and moved gantry forward and back without any problem. After connecting and tightening belt there is some juddering depending on the speed that I move the gantry from left to right and back again. There is no juddering when moving at low speed. Have checked the belt and the pulley wheel. No issues with either. Could it be an issue with the motor? Thanks guys.
