<p>I have an SKR PRO control board with a dead (shorted, it's burning hot) main processor. I ordered a new board, it was my mistake.</p>

<p>I am trying to control a laser with the fan (D9) and ran into problems.
So I tried P44, no good then P6 also not good.\
What my problem is I am trying to "burn" a group of vertical lines spaced about 0.75" apart, and randomly the drive to the laser power supply is either "skipping" (missing the control pulse) or str... | <p>Thank you all for your suggestions and help.</p>
<p>It appears that I was just running the printer too fast and slowing it down to about 10% of my original speed "fixed" my problem.
I don't know where i got the rediculous speed from, but 1200 mm/min is WAY too fast.
More like 150 to maybe 200 mm/min is what it shou... | <p>This is a stab in the dark but maybe the Arduino (clone or genuine) and RAMPS1.4 combination is not powerful enough to handle the calculations required to control the laser and printing simultaneously (although I can't really see why the additional processing to control a laser would be over taxing the processor.

<p>I have a start of a webapp that I wrote without using the Object Oriented features of PHP.</p>
<p>I don't really know if it is worth it to go back and rewrite the parts I have finished. Is object oriented PHP worth rewriting all or part of a decent working app?</p>
| <p>Given that you have an incomplete app I would say that reworking it into an Object based app will probably be helpful. </p>
<p>One thing to consider is the expected size of the end application. Below a certain complexity Object based may be overkill except for the learning experience.</p>

You might be able to come up with something, but without first creating a temporary file, it might still be difficult.
