Hi All, In my workshop I seem to have scrounged up some ~3.8mm clear plastic material that appears, at first glance, to be perspex. It has clear(ish) protective film on both sides. It appears to be very like perspex until you try to laser it. At that stage, and with similar settings that I'd use for...

Nice one Dave - that's most helpful. I had another suggestion offline, which went like this. "Capacitors inside the power supply may have degraded, such that the PSU draws more current. This greater draw heats up the connection and eventually blows the fuse." I don't like this for two reas...

An update! I've taken apart the socket, and discovered that there are three pieces of metal that make up the live "in" pin. One that engages with the kettle lead, another that acts as a bridge, and a third that holds the end of the 1 amp fuse. Now if it was me designing this, I'd make sure...

Hi All, The 1 amp fuse in the main "power in" socket in one of of my HPC 3060s just blew. Why? A bit of poking around revealed something alarming! The live socket of the kettle lead that supplies it was partially melted, as was the live "in" pin. No bad connections were made in t...

Thanks Dave!

Any idea where I could get such bearings from?

Cheers,

James

Hi All, I've just had the pulley wheel bearing on one of my 3060s wear out. (Yes, I have used it a lot.) It's a plain aluminium pulley wheel (not toothed) which tensions the 10mm drive belt. It's got flanges on either side to stop the belt skipping off, so the total width is 13mm. It sits on a 5mm s...

Thanks Dave - Whoops! Looks like I should have put this post in "Help or Advice Required"!

Hi Blackpug, My view: don't touch B&Q MDF, only buy Medite! And ask for "sanded" not "unsanded". (They may both be specified as "3mm" - but sanded is 3.0 mm, whereas unsanded is "about" 3.2 mm. If you have to buy another brand, (eg: Medite don't do 2mm) th...

Hi All, A few days ago I had a strange effect on one of my 3060s when I was getting reduced power and a "shadow" at some angles on the cut. (Say I cut a circle, there's be a feint shadow circle, too, about 3mm to the left.) "Reflection!" I thought, and checked alignment, cleaned ...

My suspicion is that MDF is quite peculiar compared with other materials. Because it generates so much smoke, the harder you cut it, the more smoke it produces, so the worse it cuts. I've spent many, many hours messing around with MDF settings. Sometimes MDF doesn't cut well in a horizontal straight...
