Very generous offer anyway. Thank you.
Just a follow up on the problem I was having with the HBP not heating up and giving false temperature readings.
As promised I have found the **culprit to my woes** in the form of a capacitor on said HBP after de-soldering and cleaning the pads on which it sat ,I measured the capacitance with a meter and got a reading of 1007uf ( Now Im no electronics wizz and I have only picked up tips from people kind enough to help me ) So don`t take the capacitor value as accurate if possible measure it yourself or get someone in the know to help.
Having said that I re-soldered the offending item back onto the HBP and hey presto it worked! ( well for a good few hours anyway).
Whilst it was working I found it to be very accurate temperature wise. I checked this with a laser temperature gun.
It was very worthwhile changing the thermistor for the 100K NTC.
I think the problem was a dry joint together with a faulty capacitor as it has since died.
I have now received a new replacement HBP from CTC so, it pays to be tenacious, only got one by going back through ebay; CTC won`t reply to you if you try to contact them directly.
This new HBP also needs the thermistor changing as the temperature is way off.
I will repair the old HBP with a replacement capacitor and I`ll then have a spare.
Hope this information is useful to others who may experience this same problem; simple fix when you know what the problem could be.

Glad to here you have got it sorted. Forgot to mention when I upgraded to my home build HBP I also upgraded the power supply. I’m in the middle of building a XL ctc but running on Arduino and ramps 1.4 (still struggling with firmware (not been well back trouble put me in hospital for 2 week)). My work shop is in the loft with ladders as access so it’s been put on hold until I’m well enough. Pic so far.
Hello Sir,
Thanks for your comment. That looks a great machine have you cut the cabinet yourself; acrylic is it?
Just trying some ABS having problems sticking to bed, Im using a glass bed with glue sticks think my problem is the new heat bed not reaching 110C. I have not yet fitted the new thermistor and the original supplied on the board just dosnt do the job.
Still practising. Sorry to hear you are unwell I know what back trouble is like suffer from it myself not long had an epidural ( Don`t recommend as it did me no good at all) Hope you recover soon.
