What I found on my little tractor was, it did shake a bit too much causing grate clogging. Along with that came with too much ash in the pot to prematurely. The automation we build is very touchy, it takes a bit to tune it to the fuels used. But once this is set up the machines are very consistent. But fuels also need to be sized consistently for this to work.
One other note is our grate rotates instead of hanging inside the ash pot. So a different set up might work better in this scenario.
Yeah, its been a very difficult year, we've been busy but funds have been tight with development cost (manufacturing and product wise). However, we have ironed out all the issues we have suffered in the past for this year. Development is fully complete on the M-Series machines and the ES machines only have some manufacturing process we need to work out. This will be the first year I can work on development for future product lines instead of on the fly.
So my only hold up this year is funding, If I have I will be there. Ill make time to make it
