How to Repair a CNC Control

(Step 1

Approach the ailing control in a confident manner. This will give the control the mistaken idea that you know something. It will also impress anyone who happens to be looking, and if the control should suddenly start working you will be credited with its repair. If this fails to work, proceed to step 2


--------------------------------------------------------------------------------

Step 2

Wave the service manual at the control. This will make it assume that you are at least familiar with the source of knowledge. Should this fails to work, proceed to step 3


--------------------------------------------------------------------------------

Step 3

In a forcible manner, recite ohm's law to the control (CAUTION *** Before taking this step, refer to some reliable handbook to be sure of your knowledge of ohm's law). This will prove to the control beyond a shadow of a doubt, that you know something. This is a drastic step and should be attempted only if the first two steps fail. If this fails to work, proceed to step 4


--------------------------------------------------------------------------------

Step 4

Jar the control slightly, this may require any thing from a three to six foot drop, preferably on to a concrete floor. However, you must be careful with this step because, While jarring is an approved method of repair, you must not mar the floor. Again this is a very drastic step. If it fails, proceed to step 5


--------------------------------------------------------------------------------

Step 5

Wave a large screwdriver in a menacing manner. This will frighten the control and demonstrate your knowledge of the deadly "Short circuit technique." Proceed to step 6


--------------------------------------------------------------------------------

Step 6

Add a tube...Even though the control is solid state. This will prove that you are familiar with the controls design. This will confuse the control and thereby increase your advantage. If this doesn't work, proceed to the most drastic and dangerous step. It is seldom needed and is a final resort if all else fails!!

great post!

there is something wonderfully reassuring abt.being able to visually inspect a mechanical device for damage/failure.....yeah,yeah iknowabout occilloscopes(sp?) i have an amateur extra license & am supposed to know something abt. electr.theory /repair HA!!!!!plastic is continually giving me problems as well! it doesnt braze worth a d---.it was nice when u didnt need a several thousand dollar test machine & thousands of dollsrs of SUBSTITUTEparts to diagnose ur hiccuping engine!!! do u remember when water pumps had grease fittings;my 48 INt.M still has original pump&RADIATOR!! front ends ,universals W /fittings?....now deceased curmudgeon friend had no spark on 76 ford whenleaving;(bad module), borrowed my truck & returned next day w/74 ford distributor w/points & cond.muttering about 100dollar modules& 5 dollarpoints!even if u dont want to spend 2 days making a 20dollar part when all that u need is a .50 washer,but not sold separately,it is a good feeling to have the option!( &not have to purchase a$125 mini computer as well.do u also remember when there was enuf room in engine compartment to crawl in & work on thinges & changing plugs was not inthe flatrate book @3 hourstime!!!!progress! best wishes

Yes, the great dilemina of the modern machine...those pesky silicon chips. There are a few complex but fully mechanical machines still being made..small diesels used on sailboats for one, but the list is growing very short indeed.
